Some people can stand (on the ground), bent over at the hips until their chest is horizontal, and still pick their one foot off the floor until their knee hits their chest.Īll these years, I thought I was a lousy climber. It’s just gearing, like a chainwheel size change. People say that shorter cranks give you a lower power output, but that is not true. The thing I think is most important to understand is that if a crank size exceeds your fluid range of motion, you may as well be riding with the brakes on.
From what I understand, the tiny 8% size range of cranks for adults comes from high-wheel racers from 130 years ago. My 5’2″ wife has had 140’s on her mtb for years, made by a machinist who shortens and sells them online. Nothing but improvement in speed and reduced hip pain. Last month I put a set of 153’s on my mtb. Hill climbing, based on gps history, improved a lot both in speed and comfort. My bikes come with 175s, 8 years ago on a whim I installed 170s on my road bike. I have moderate flexibility issues, 6’2″ tall. Retail price for either 1x or 2x setups appears to be the same at $178 / 178€ including rings – with claimed weights of 751g (50/34T x 170mm) & 730g for 1x (40T x 170mm). The cranks feature 30mm 7050 forged alloy spindles to for 386EVO bottom brackets. This also means these can go subcompact for gravel & off-road too, with current 50/34T, 48/32T & 46/30T ring combos available in FSA’s 120/90mm 4-bolt BCD. FSA already offers 36, 38, 40, 42 & 44T Thick-Thin (narrow-wide) single ring setups in this BCD. That suggests a wide range of chainring options. The oversized cold forged 6061-T6 alloy arms both appear to share the same 145mm Q-factor, somewhat unique 120mm BCD chainring sizing in 1x or 2x configurations. The new Gossamer Pro BB386EVO cranks now offer a wide range of lengths across both 1x & 2x setups – 145, 150, 155, 160, 165, 167.5, 170, 172.5 & 175mm arms available! But smaller riders will obviously benefit too! They were in fact developed in response to Vision-sponsored tri pros who want shorter cranks to allow “shorter movement of your leg… creating less turbulence and therefore more aerodynamics performance” and pedaling more “similar to the movement of the leg during the running phase, therefore it creates less physical decompensation allowing the rider to face the last phase of the race in optimal way”. The $96 / 104€ Energy Super Compact features the same subtle 4° outward bend (not angled flare) to make room for your arms in the drops, but now gets a slightly more compact 120mm drop & 70mm reach, again to better fit smaller riders & juniors.įSA Gossamer Pro alloy road crankset fit gets super short & sub-compact It includes internal routing compatible with both semi-integrated ICR & fully-internal ACR stems.
The double-butted 7050 alloy bar gets a 110mm wide x 31.8mm round clamping area that transitions to slightly flattened 34mm ergonomic flat tops. Less fancy looking but still high-end for an alloy dropbar, the FSA Energy goes Super Compact, adding new 36cm & 38cm options for smaller riders (in addition to standard Compact 40, 42 & 44cm bars, all measured center-center at the bar ends), with a weight claim of 255g (38cm).
With 115mm drop & 75mm reach, the 31.8mm clamp dropbar now comes in 40, 42, 44, 46 & 48cm widths (~5cm wider c-c at the drops) with a claimed weight of 205g (42cm).įSA Energy alloy road handlebar fit goes Super Compact
