FSA dials in personalized road and gravel bike fit for 2021 with broader sizing options across existing alloy & carbon bars and alloy cranksets. In a bid to give riders a more customized bike setup with truly individual fit, FSA has substantially expanded size offerings – going big the K-Wing AGX & small for Energy handlebars, and super-short, sub-compact Gossamer Pro 1x & 2x cranksets…
FSA K-Wing AGX aero gravel handlebars go wide
The 2021 update to the carbon K-Wing AGX aero gravel handlebar is the most straightforward out of the bunch here, adding two wider options to the premium flared dropbar for riders looking for more control off-road. Measured center-center at the hoods, the K-Wing AGX now adds wider 46cm & 48cm options, on top of the original 40, 42 & 44cm bars (apparently truly 3.5mm wider at the shifter mount).
The UD carbon, 12° flared carbon bar sells for $314 / 314€. It features 5mm rise at the aero wing tops, a sculpted ergonomic section in the bends for comfort behind the brake hoods, and Di2-ready internal cable routing ports that are compatible with all of FSA’s ICR or ACR stems/headsets for semi-integrated or fully-hidden completely internal cable routing.
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).
FSA Energy alloy road handlebar fit goes Super Compact
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). 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. It includes internal routing compatible with both semi-integrated ICR & fully-internal ACR stems.
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.
FSA Gossamer Pro alloy road crankset fit gets super short & sub-compact
The update of the long-running Gossamer Pro alloy crankset may be the biggest move towards offering more customized fit options. Conveyed to us as offering shorter cranks arm lengths ideal “for triathlon usage”, there’s plenty of potential benefit here beyond Ironman racing.
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”. But smaller riders will obviously benefit too!
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!
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. That suggests a wide range of chainring options. FSA already offers 36, 38, 40, 42 & 44T Thick-Thin (narrow-wide) single ring setups in this BCD. 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. The cranks feature 30mm 7050 forged alloy spindles to for 386EVO bottom brackets.
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).
