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

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:

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.

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

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.

Shimano's revamped deore xt brake caliper uses a two-piece forged aluminum body with advanced heat management features that include 22mm-diameter ceramic pistons and finned brake pads: shimano's revamped deore xt brake caliper uses a two-piece forged aluminum body with advanced heat management features that include 22mm-diameter ceramic pistons and finned brake pads

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.
