Recta Final – Crank Brothers Cobalt 3

On 2011-08-08, in Blog, by Ruben

Em 2007 comprei a minha bicicleta suspensão total,  e cedo comecei a modifica-lá, tendo em vista manter o conceito de bicicleta “marathon/all  mountain”, melhorar a estética e reduzir o peso, claro que a estética é sempre subjectiva, depende dos gostos de cada um.

Agora em 2011 cheguei ao ponto que durante estes anos não via chegar, o ponto em que digo “já está”, já não necessita de nada, é a bike dos meus sonhos (dentro do que as finanças permitem e note-se que no meu sonho tinha mais de 20 bikes) e esse ponto é quando compro a última peça, a peça que mais dinheiro custa, as rodas (já que o quadro veio na compra da bike).

No fim de semana vou ver se as monto na bicicleta e depois apresento o resultado final.

Um muito obrigado a todos aqueles que me têm acompanhado e ajudado nas compras, escolhas, etc.

PS: A crank brothers anuncia um peso de 1500g para o par e o verificado foi 1562g (F:707g; T:855g)


Novidades Suntour 2012

On 2011-07-21, in Blog, by Tigas

Mais novidades para 2012, desta vez da Suntour.

Bem sei que muitos de nós não gostamos mas estas marcas “alternativas” cada vez mais têm produtos interessantes e a um preço excelente!

Pessoalmente tenho uma RST F1 Patinum e não troco por nada … 100mm, 1450g e … 290€ … tirem as vossas conclusões!

With forks and shocks from the big three – RockShox, Fox and Marzocchi – becoming ever more expensive, and poor suspension being the Achilles’ heel of many a budget mountain bike, the need for decent mid- and entry-level dampers is greater than ever.

That’s where Taiwan’s SR Suntour come in, with an ever-improving range of aftermarket products to complement the OEM parts they supply for complete bikes. For 2012 they have three new top-of-the-range forks and two new shocks. Here’s a quick look…


Suntour’s three top forks all get lighter (157g vs 237g) and more sensitive damping cartridges for 2012, new titanium 15mm Qloc axles which save another 60g (70g vs 130g), and updated air springs, with more of a ramp-up at the end of the stroke to avoid harsh bottoming out. All prices TBC.

Epicon X1 LO RC

The Epicon is Suntour’s all-mountain/trail offering, with 120/140/150mm of travel. It’s available with a 1-1/8in or tapered steerer; the latter has a new hollow crown. A 29er version is also available, with 100/120mm of travel. Claimed weights are from 1,600g for the 26in version and 1,670g for the 29in. The fork has a lockout (remote version available) plus adjustable rebound and low-speed compression damping.

Durolux RC2

Bigger-hitters should check out the heavier-duty Durolux. Weighing in at 2,220g (claimed), this is available in adjustable (120-160mm or 140-180mm) or fixed travel (160mm or 180mm) versions, with a 1-1/2in, tapered or 1-1/8in steerer. The new RC2 damping offers adjustable rebound plus high- and low-speed compression.

Axon Werx RC

For cross-country/marathon race whippets there’s the Axon, with 80-100mm of adjustable travel and a claimed weight of 1,490g. The top-end RC model comes with a choice of remote or electronic lockout, new carbon/magnesium dropouts and, on the tapered steerer version (standard 1-1/8in also available), a hollow crown. Rebound and low-speed compression damping are both adjustable.

Epicon RC2

Suntour’s rear shocks follow the same naming convention as their forks, so the Epicon RC2 is a trail/all-mountain unit with adjustable rebound (R) plus high- and low-speed compression damping (C2) – an improvement on this year’s models, where compression was preset. The 2012 shock is also lighter (200-220g, claimed) and features an improved air spring. It’ll be available in 165, 190 and 200mm lengths, with 38, 50 or 55mm of travel. Suntour haven’t released a picture of the RC2 yet.

Durolux RCA

The Epicon shock’s bigger brother is the dual air chamber Durolux. This offers eight steps of compression adjustment compared to six on the 2011 model, and you can now adjust both the low-speed and high-speed damping. Claimed weight is from 275g. It’ll be available in 190, 200 and 215mm lengths, with 50, 55 or 63mm of travel.

BTT – Specialized 2012

On 2011-07-13, in Blog, by Tigas

Fica a nova linha da Specialized para 2012 … será que é desta que me vendo ao S?! ;)


Specialized’s latest redesign of the 30-year-old Stumpjumper is the biggest news for 2012, but they also have new carbon Camber and alloy Carve 29ers, as well as a new entry-level downhill rig, the Status, which is a replacement for the stalwart Big Hit model.

At their global mountain bike launch in Monterey, California the ‘big S’ also unveiled some key upgrades to the Epic full-suspension range and carbon Stumpjumper hardtails – the most significant change being a crown-mounted Fade adjuster for the SID Brain fork found on the S-Works, Expert and EVO R models.

Stumpjumper FSR

At its launch 30 years ago, the Stumpjumper was one of the first bikes ready to hit the trail right out of the box, at a time when many ‘mountain bikes’ were still cobbled together from ‘clunker’, road bike and motorcycle parts. Fast forward to the coming season, the 2012 model year, and Specialized are again making Stumpjumpers to fit many different riders and styles of riding right out of the box. There’s an M5 alloy hardtail – more on that below – along with both alloy and carbon FSR full-suspension bikes.

The new Stumpjumper FSR will undoubtedly be Specialized’s most versatile model. It’s built with their ‘trail geometry’, which is defined by a lower bottom bracket, slacker head angle and shorter chainstays than their cross-country race bikes, and available in carbon or M5 alloy, with 26in or 29in wheels. There are also heavier-duty Stumpjumper FSR EVO models in both wheel sizes and frame materials.

With their latest redesign, Specialized are asking riders to think again about the Stumpjumper. The new bikes all sport contemporary features including tapered head tubes, PressFit 30 bottom bracket shells with ISCG05 chain guide tabs, 142+ rear through-axles, sealed cartridge bearing pivots with captured hardware, internal dropper seatpost cable routing and direct post mount 160mm brake tabs.

All of the standard Stumpjumper FSR models will also come with a new chain retention device called the Dangler – a low-friction, 30g chainstay slide glide built using composite plastic technology borrowed from KTM motorcycles. While the Dangler looks low-tech, during our rides at the launch it did an admirable job keeping the chain on and goes unnoticed while riding; it’s quiet and doesn’t add any perceivable friction to the system.

The proprietary Dangler chain device is so quiet you don’t notice it when riding

While there are 10 models in the new Stumpjumper FSR line we’ll look at two to give a frame of reference: a standard Stumpjumper FSR and an FSR EVO.

S-Works Stumpjumper FSR Carbon

The S-Works Stumpjumper FSR Carbon is available with 26in wheels and 140mm of travel, or 29in wheels and 130mm. We took a ride on the 29er version. This top-of-the-line, break-the-bank bike rides as a machine nearing the US$10,000 mark should – extremely well. It’s light, and the components have been well thought out – 720mm wide low-rise bar, Specialized Command Post BlackLite dropper seatpost, Fox Racing Shox Kashima suspension (with Brain inertia AutoSag damper for the rear) and new Roval Control Trail SL carbon wheels with 28mm OD rims.

This is all icing on the cake, as the bike’s well sorted geometry (69˚ head tube angle, 450mm chainstays, 338mm bottom bracket height/34mm drop) was the star of our brief test ride, during which it handled beautifully. While the S-Works bike is attention grabbing, there are few who can afford to drop that type of cash on a mountain bike, which is where the M5 alloy models come in – these start in the mid-$2,000 range. Carbon bikes with a decent but more subdued spec start at around $4,000.

The antitheses of the S-Works bikes are the EVO models. Specialized will offer three complete EVO bikes for 2012: one with 29in wheels and two with 26in wheels. The EVO trail bikes are defined by their slacker angles (for example the head angles are 67˚ versus 68˚ for the 26in bikes, and 68˚ versus 69˚ for the 29ers), additional travel (150mm front and rear for the 26in bike; 140mm front, 135mm rear for the 29er) and gravity focused suspension and build.

Stumpjumper FSR Comp EVO

The FSR Comp EVO is the most economical bike in the EVO line and will sell in the mid-$2,000 price range. It comes with a hydroformed M5 alloy frame, which has a claimed weight of 2,415g without the RP2 AutoSag damper. A RockShox Revelation fork with 20mm axle and Motion Control RL DNA damper complements the 150mm FSR rear suspension system. With a flick of the lockout levers the bike climbs respectably and it’s a hoot on the descents; the extra 10mm of travel, bigger tires and slacker angles are immediately noticeable. The bike also sports a Command Post BlackLite dropper post – a real bonus considering the price.

AutoSag rear shocks

All of the Stumpjumper FSR models use a new shock setup design that automatically adjusts the rider’s sag to 20 percent in four easy steps: open the compression adjustment; overfill the shock by 30-50psi; sit on the bike and press the auto sag button, emptying the negative chamber; cycle the shock to automatically refill the negative chamber and you’re ready to ride.

AutoSag uses an existing transfer port found on the outer air can of Fox’s Float shocks but adds an additional ring type chamber with a second valve. This allows for the negative chamber to be bled, and under a rider’s full weight the bleed sets a fixed sag – in this case 20 percent – based on its engineered location.

Once sag is set and the shock is cycled the valve can be used to release air to fine-tune the shock, without fear of emptying the shock, as you would if you were bleeding from the main chamber without a pump. The AutoSag shock can also be set conventionally using a shock pump and O-ring. The point of the technology is to make sure all Stumpjumper FSR riders get the most from their bike’s suspension.

Stumpjumper hardtail

While the Stumpjumper carbon hardtail frame carries over from 2011, the M5 alloy model – aimed at performance-minded riders on a budget – has been completely redesigned. It’s inherited many of the features found on the carbon bike: a tapered head tube, direct post mount 140mm brake tabs and PressFit30 bottom bracket shell, plus thin seatstays and a 27.2mm seatpost for a softer ride when seated. The Stumpjumper M5 will be offered in Comp 29 and EVO 29 trail dress, as well as a single Comp 26in model.

Carve 29er

The all-new Carve takes the economical purpose of the M5 Stumpjumper yet a step further. There are three M4 alloy models in the line, all with 29in wheels, with prices ranging from $1,300 to $1,700. Designed to slot in between the Stumpjumper and Rockhopper ranges, the bikes offer tapered head tubes, tapered seat tubes and a bridgeless ‘vertical flex stay system’ paired with a 27.2mm seatpost to better their comfort.

Camber carbon 29er

Specialized launched the Camber full-suspension bike last year. The big news for 2012 is three new carbon 29er models. The seven-model Camber range splits the difference between the Stumpjumper and Epic lines in regards to both travel and geometry, with 110mm of travel and a 70˚ head angle for the 29in models and 120mm and 68.5˚ for the 26in bikes.

The Camber sports all of the features found on the Stumpjumper FSR, including a tapered head tube, internal dropper post cable routing, PressFit30 bottom bracket, 142+ rear through axle and direct post mount 160mm rear brake mount. M4 alloy Camber models will be available in both 29in and 26in wheeled models, starting at $1,700.

Status DH

The Status is a replacement for the venerable Big Hit downhill/freeride bike, with an all-new, 200mm-travel M4 alloy frame built with geometry adopted (and adapted) from the Demo; it sports a lower bottom bracket and slacker head angle than the Big Hit. The FSR suspension is also newly modified, with a linear shock rate which, combined with the geometry, is said to make it a much more capable downhill race bike. The Status is aimed at new gravity riders, whether they’re kids or senior riders and looking to race or just run laps in the bikepark.

It uses a 1-1/2in head tube and runs bearings in all of its pivots (save for the forward shock mount). It’ll be offered in two models: Status 2 and Status 1. The former runs just over $3,000 with a RockShox Domain dual crown fork and Fox DHX RC damper. The Status shares forgings with the SX Trail, and while both models come with a single ring and chainguide, it’ll accept an E-Type front derailleur. Out back the bike has 135mm spacing with simple open quick-release dropouts, though both models come with bolt-on hubs.

Reba RLT 120mm

On 2011-07-07, in Blog, by Tigas

Uma suspensão a ter em conta em futuras aquisições …

RockShox Reba RLT Ti 120mm suspension fork

The Reba was updated with a 20mm Maxle axle, power bulged and post-mounted brake lowers a while ago, which makes it one of the stiffest steering and braking 120mm forks available. It’s not light and there’s no 15mm axle option so you’re restricted to a generally heavier range of wheels unless you go quick-release and give up stiffness.

It can be shimmed down to 100mm or 80mm of travel, and dual positive and negative air chambers let you set up the initial stroke as plush or as tight as you want. The BlackBox damping in the RLT Ti version is good too, with the titanium damper body giving more oil volume and shimmed big hit control.

Add in the chassis stiffness and this is a fork that proves its mettle by being pushed hard through the most testing sections that most longer-travel forks would faint at. RockShox’s remote lockouts are the most ergonomically efficient and their reliability reputation is excellent.

Btteco no Regional de Santarém xcm

On 2011-06-27, in Blog, by Paulo986

No passado domingo fui-me por à prova em Granho, na 2ª etapa do regional de Santarém de xcm, participando na meia-maratona, 40km.

Sabia que me ia esperar um inferno, pois as previsões eram para 40ºC e confirmaram-se e a partida estava marcada para as 10h00m

O percurso era duro, com muito sobe e desce na primeira parte, uns estradões pelo meio e singles no final, com muita pedra solta, areia e um terreno muito duro!

Só decidi participar nesta prova a meio da semana e não tinha treinado grande coisa, mas mesmo assim decidi arriscar!

Deixo aqui o rescaldo que fiz no forum btt:

Secretariado – 4/5 – Sem grandes problemas!
Partida – 4/5 – Controlo zero, box’s a dividir as várias classes, partida a horas, mas sem nenhum sinal!
Percurso – 5/5 – Gostei muito, durinho, muito tecnico, muito sobe e desce nos primeiros km’s, alguns estradões, e para o fim single-tracks! Gostei mesmo!
Controlos – 5/5 – Controlo zero como já referi e cerca de 5 postos de controlo durante 40km, muito bom
Marcações – 5/5 – Muito bem marcado, fitas, placas em todas as viragens, placas de perigo!
Abastecimentos -/5 – Só retirei agua, não reparei no que tinha, no abastecimento na meta é que podia ter uma bebida isotónico, para recuperar um pouco das forças!
Chegada – 5/5 – Comissários da FPC a controlarem os tempos, que saíram pouco depois da chegada dos primeiros da meia!

Quanto à minha prestação:

Parti na 3ªbox atrás dos federados, sub23/elites e vetaranos A, os primeiros km em alcatrão foram feitos a um ritmo impressionante e eu consegui-me aguentar nos primeiros grupos, ao entrar no primeiro estradão fez-se uma nuvem de pó que não se via nada, houveram quedas nessa altura.
Fui-me aguentando num sobe e desce em pedra solta, em que as subidas eram feitas à mão e as descidas com muito cuidado pois eram muito técnicas.
Por volta dos 15km comecei a pagar a factura de ter abusado no inicio e comecei a quebrar, com cerca de 42ºC, coloquei um ritmo mais baixo durante 10km e aos 25km comecei outra vez a carregar e ganhei muitas posições!

Ficando assim com a seguinte classificação na categoria: promoção,sub23/elites:

1 Claudio Trancadas-Bike Clinic 01:38:07
2 Diogo Modesto-Trilho Perdido/BarboRacing-01:41:22
3 Angelo Vieira Pisco-Moçarria Aventura Clube-01:44:28

Wahoo Fitness para iPhone

On 2011-06-24, in Blog, by Tigas

Ando a “namorar” esta solução faz mais de um aninho ;)

Agora com caixa incluída… não me parece que vá resistir!

Wahoo's $149.99 'bike pack' has all you need to turn your iPhone into a fully featured data capture device

Chip Hawkins started Wahoo Fitness18 months ago with an ANT+ adaptor, or key, for the iPhone. His goal was to develop a better way to capture ride metrics — namely GPS and power data, among others — and share them quickly and easily with other software systems.

“I came up with three requirements,” said Hawkins, Wahoo’s founder and CEO to BikeRadar. “I had to get ANT+ into the iPhone; I needed a case that’s waterproof and can safely mount on a bike, and I needed software.”

In February, Wahoo launched their waterproof handlebar mounted case for the iPhone. The key, however, was the software. “We released our API (Application Program Interface) out into the public so that the likes of RunKeeper, Map My Ride, Map My Run could write to our API and therefore communicate with the iPhone,” said Mike Stashak, Wahoo’s vice president of marketing. “Basically it’s a little piece of software that allows iPhone language speak ANT+ language rather than having Map My Fitness try to figure out iPhone language; all they have to do is ask for speed data, or GPS, or power data. [After that] we had all of these fitness apps writing to our hardware and selling it to their user base.

Wahoo's original ant+ key:

Wahoo’s original ANT+ key

According to Wahoo, that’s just the tip of the iceberg. “The second thing we did was wrote our own app,” said Stashak. “All of the apps out there were great for the mass market, but for the real experts of the cycling world we needed to write our own app to showcase all of the functionality of the iPhone with ANT+ because right now you might just think you can use your iPhone as a bike computer.”

The real advantages come with the computing power housed within the iPhone. That power along with its all-the-time connectivity is highlighted by Wahoo’s Fitness App and ultimately makes downloading a ride, along with all of its metrics, including, GPS, power, speed, ANT+ heart rate, cadence and more, a simple one touch process.

Additionally, the information can be sent to multiple software systems at the same time, say,Training PeaksStravaGarmin Connect and email the actual data files all at the same time. “It’s a real data junkie’s app,” said Hawkins. Beyond Wahoo’s own app, there are 60 third party apps available that work with the iPhone and Wahoo’s ANT+ function.

The wahoo fitness app offers one-touch uploading to all of your analysis software at the same time:

The system also offers the ability to upload real time telemetry to the web, via Map My Tracks so that anyone online can watch exactly what you’re doing on the bike in real time.

The current iPhone 4 is good for roughly 3.5hrs of use when using ANT+, GPS and screen during a ride; GPS and Internet are the big power draws. Along with the ANT+ transmitter and a bar mounted case with incorporated ANT+ (you only need one), Wahoo also offers and external battery, which they say adds 6hrs of run time, for a total of over 9hrs.

The case features a rubber lined cradle and 6-latch touch through clear cover :

The bike case has an ANT+ key built in

The system works with 3GS and 4 iPhone models and all ANT+ plus accessories. The ANT+ transmitting ‘bike case’ alone costs US$119.99, while the ‘bike pack’ costs $149.99 and includes the case and mount along with speed and cadence sensors. Wahoo’s high-powered app is free through iTunes. Wahoo also sells a heart rate strap for 49.99. The external battery will be available in August for $59.99. They even offer a time trial bar mount for $19.99 that sits between the aero extensions.

Post do Paulo no

Está feita mais uma edição da maratona de Cuba, gostei, para mim correu tudo bem e a organização está de parabéns, muito calor, mas água nunca faltou!
Participei nos 70KM e que médias impressionantes se fizeram!! O percurso também era propicio a tal…

Deixo aqui o meu rescaldo, da Maratona (70KM)

Secretariado – 5/5 – Rápido e eficiente
Partida – 5/5 – Controlo 0, a horas, com briefing, bem audível
Percurso – 4/5 – Muito rolante, com 2 subidas mais puxadas, com algum terreno mais puxado, poucos ou quase nenhuns single tracks, descidas porreiras!
Marcações – 4/5 – Não me perdi, mas achei em algumas zonas as fitas muito distantes, de resto placas com sinalizações de perigo, setas!
Postos de Controlo – 3/5 – Como já disse, cotrolo 0 e mais 2 postos de controlo
Pessoal da organização no percurso – 5/5 – Muito pessoal, em todas as passagens em estradas estava gente
Abastecimentos – 5/5 – Não parei em nenhum, mas só pelo facto de haverem muitos pontos de água no percurso, espectáculo, com o calor que se fazia sentir, levam nota máxima
Chegada – 5/5 – Tudo normal
Lavagem de bicicletas – 4/5 – Mangueiras suficientes, mas com pouca pressão, deu para tirar o pó
Banhos – 4/5 – Tomei nas piscinas, o espaço era muito bom, mas os chuveiros eram um misto de água fria e água a ferver

A organização leva nota positiva, muito simpática e atenciosa!

Foi uma bela e dura manhã, devido ao calor!

Primeiro teste ao novo Grupo Shimano XT

On 2011-06-15, in Blog, by Tigas

Cá está o primeiro teste ao novo Shimano XT … acho que vou começar a poupar dinheiro ;)


Shimano created some serious waves with their latest-generation XTR group, what with its fantastic brakes, ultra-smooth shift performance and impressively light weight. But not many people can afford it.

Now that we’ve ridden the new Deore XT, it seems that Shimano have managed to trickle down virtually every aspect of XTR’s functionality and feel but with a far more attainable pricetag and just a little more weight. More value-minded enthusiasts will be glad they’ve waited.

Shifting: More positive lever feel and new two-ring options but still with that familiar Shimano precision

Overall shift performance hasn’t changed much relative to the previous-generation 10-speed Deore XT group, though that’s hardly a bad thing in this case. Combined with the carryover cassette and asymmetrical chain, the revamped derailleurs and shifters again provide ultra-smooth and precise gear changes in both directions and at both ends when just spinning along or churning out lots of power. Credit out back also goes to the stout Shadow-type rear derailleur with its widely set pivots that allow less flex under load along with the new front mechs that offer similarly stiffer construction.

Shift lever feel on the new Deore XT has improved, however, with the addition of Shimano’s Vivid Index concept for 2012. Overall system spring tensions remain pleasantly light in typical Shimano fashion but the detent spring tension has increased for a more positive and tactile action. In combination, this yields much better feedback on bumpy trails than before for fewer accidental shifts while also keeping things easy on your thumbs – something most of us aren’t bothered with on everyday rides but a feature to which endurance athletes might want to pay attention.

Optical gear indicators are removable on the new shimano deore xt shifters, which will be offered in both separate and integrated versions depending on your preferences. either way, just a flick of a switch is required to convert the left-hand shifter for use on two-ring or three-ring drivetrains: optical gear indicators are removable on the new shimano deore xt shifters, which will be offered in both separate and integrated versions depending on your preferences. either way, just a flick of a switch is required to convert the left-hand shifter for use on two-ring or three-ring drivetrains

Optical gear indicators are removable on the new Shimano Deore XT shifters, which will be offered in both separate and integrated versions

While improved, lever feel is still one of the most obvious areas where the new Deore XT doesn’t quite match XTR. Without the full complement of lower-friction ball bearings like the flagship model, Deore XT’s paddles aren’t quite as uncannily silky smooth. But we’re splitting hairs here – most users won’t even notice.

Multiple shifts are a piece of cake, not to mention very fast, especially out back. Users can downshift up to four rear gears per sweep of the non-adjustable pull lever or upshift up to two cogs per swing of the stepped push-or-pull trigger. In either case, the paddles are well placed and intuitive to operate just as before. Separate pods with removable gear indicators can be positioned independently of the brake levers while a new Ispec integrated option will offer up a less adjustable but cleaner-looking cockpit depending on your preferences.

Braking: Lots more power and improved heat dissipation but a bit grabby at low speeds

Braking performance is a dead ringer for XTR across all the metrics that most users will care about, including lever feel, power and modulation. Shimano claim a 25 percent jump and until we can get a set on our instrumented test bench, that figure is wholly believable. Even with a modest 180/160mm front/rear rotor setup, we had no problems quickly and effortlessly scrubbing off lots of speed while ripping some descents. Lever action is very light, smooth, and highly communicative of what’s going on at the other end.

That power is also easily controllable, in trademark Shimano fashion. The semi-metallic pads of our test samples were remarkably quiet, squealing for just a split second after creek crossings. They were a bit grabby for our liking during low-speed technical descents where feathered modulation is key, though – we’d suggest the standard resin pads to riders who’ll primarily be riding in dry conditions.

None of these improvements should come as any surprise given the changes made. The newly compact master cylinder architecture is wholly lifted from XTR, with new stubby one-finger levers (they’ll still work with two), an Avid-like pivot layout that yields a more natural feel as you pull the lever through its arc, Servo Wave variable pivot leverage ratios for fast pad engagement and finer control, and tool-free lever reach and tooled pad contact adjustments just like with the XTR Trail levers.

At the other end lie new forged aluminum two-piece calipers with the same 22mm-diameter ceramic pistons as XTR for more even pad force application and better heat insulation for the underlying mineral oil. Shimano have even carried over the finned brake pad backing plates and three-layer stainless steel-aluminum-stainless steel rotors from XTR to further facilitate heat dissipation.

Our test rides weren’t rigorous enough to really put that new heat capacity to the test but experience with XTR suggests that the concepts work at preventing fade, and quite well at that. Shimano will offer the new Deore XT ICE Tech rotors in 160, 180 and 203mm diameters, and in both Center Lock and six-bolt variants.

Drivetrain: Familiar crank technologies with a new double option; two new pedals

Deore XT’s standard three-ring drivetrain doesn’t bring with it any major surprises. Yes, the hollow forged aluminum crankarms have revised styling but also the same familiar Hollowtech II pinch-bolt and external bearing layout. Shimano have retained the tighter 42/32/24T Dyna-Sys spacing that we’ve grown quite fond of for its smoother shifts, fewer required recovery shifts across the wide-range 11-36T 10-speed cassette, and fantastically rigid carbon-composite-reinforced steel middle chainring.

The forged aluminum shimano deore xt crank doesn't use the fancy two-tone bare polished and anodized finish of xtr but then again, it doesn't cost nearly as much. more importantly, any difference in shift performance is imperceptible, as is any gap in stiffness. shimano will offer deore xt in both 2x10 and 3x10 variants, though two-ring cranks won't offer a narrower stance width as with xtr: the forged aluminum shimano deore xt crank doesn't use the fancy two-tone bare polished and anodized finish of xtr but then again, it doesn't cost nearly as much. more importantly, any difference in shift performance is imperceptible, as is any gap in stiffness. shimano will offer deore xt in both 2x10 and 3x10 variants, though two-ring cranks won't offer a narrower stance width as with xtr

Just as before, the arms are admirably rigid, far less nerve-wracking to hammer into rocks than carbon fiber ones, and the whole drivetrain is refreshingly quiet on the trail for the most part. The one exception is that is suffers from the same levels of chain slap as before – nothing worse than the competition, mind you, but now that we’ve been given a taste ofShimano’s intriguing Shadow Plus rear derailleur design, we can’t help but eagerly await its addition to Deore XT for more silent running.

In bigger news, yes, Deore XT will now be offered with a double chainring option in 40/28T or 38/26T sizes, with specific front derailleurs to match (the front shifter includes a handy built-in switch so the same unit works for doubles or triples). Unlike XTR, though, neither features a narrower pedal stance width. We haven’t ridden with either of the doubles yet so you’ll have to wait a bit longer for our ride impressions there.

We did, however, get time on Shimano’s new Deore XT PD-M785 Trail pedals, with similarly oversized aluminum platforms to XTR. No surprises here, either: cleat engagement and release are positive and direct as always but the larger platform is more supportive of softer-soled shoes like the Pearl Izumi X-Alp Elite. Though heavier than XTR, the Deore XT option is of course cheaper and with little penalty to show for it – and there’s also a revamped, lighter ‘Race’ pedal that we’ll sample a little later.

Wheels: New tubeless-compatible Race and Trail editions with expanded axle fitments

In keeping with the theme, Deore XT’s new wheel offerings will include a lighter Race edition and a tougher Trail one. The former uses a lighter 19mm-wide (internal) rim to help reduce rotating weight while the Trail wheelset gets a more substantial 21mm dimension for better support of wider tires. Both get UST tubeless-compatible rim designs with solid outer walls, Shimano’s trademark brazed-on threaded nipple anchors and steel freehub bodies.

As with xtr, the new shimano deore xt wheelsets will be offered in both trail and race variants (both in 26in). the trail model uses 21mm-wide (internal width) rims while the race model uses slightly lighter 19mm ones - and both are fully ust-compatible with no rim strips required: as with xtr, the new shimano deore xt wheelsets will be offered in both trail and race variants (both in 26in). the trail model uses 21mm-wide (internal width) rims while the race model uses slightly lighter 19mm ones - and both are fully ust-compatible with no rim strips required

Both Shimano Deore XT wheelsets use welded rims with brazed-on threaded nipple anchors that allow for a solid – and fully UST-compatible outer rim wall for easy tubeless setup

Both also use smooth-rolling adjustable (and easily serviceable) cup-and-cone axle designs with angular contact bearings. Trail edition wheels will be offered in either 135mm quick-release or 142x12mm through-axle rear fitments plus 15mm through-axle front fitments only, while the Race edition will be offered in rear quick-release only but either quick-release or 15mm through-axle at the front.

We’ve only sampled the Trail wheels so far and it’s too early to pass judgment. We will say, though, that the relatively fast-engaging freehub body (the same as last year’s as far as we can tell) rotates with little friction so there’s little chance of dropping a chain with a quick reverse pedal stroke, overall rigidity is admirably high and seemingly in keeping with XTR, and the UST rim design holds on so solidly that it can actually be difficult to strip tires. Stay tuned on this one, folks.

Overall: Fantastic example of trickle-down technology

Mountain bikers who have been smitten with XTR’s performance but not its pricetag will be happy they waited for the flagship group’s features to filter down to Deore XT’s more commoner-friendly cost. Aside from some extra weight, an ever so slightly less refined shifter feel, and the lack of a narrow-stance crank, the new Deore XT is a dead ringer for Shimano’s top dog. Patience is a virtue, indeed.

BTTecos em Torres Vedras

On 2011-05-23, in Blog, by kreisp

No último Sábado 2 BTTecos foram até Torres Vedras à 1ª Maratona BTT Oestebike Continente.

A organização esteve a um nível bastante bom.
Speaker, Partida a horas, controlo zero, marcação excelente, altimetria como deve ser, boas ofertas, balneário em condições, etc, etc.

Este tipo de organizações embora tenha um preço um pouco mais elevado, faz uma diferença enorme para outras organizações amadoras!

Percurso duro mas lindo e técnico, com muito sobe e desce e paredes para subir.

No final alcançámos o 14º e 15º lugar que muito nos agradou :)

Ainda estivemos à conversa com o nosso fornecedor de equipamentos, que nos confessou que achava o nosso um dos mais bonitos! (cores sóbrias, discreto, etc:)
