Full Speed Ahead (FSA) has updated its Gossamer alloy chainset, and is now offering it with new crank arm length options which go as short as 145mm - while Vision has released the Metron TFE Pro Clip-on Extensions, that have been tried and tested with race-winning success in the pro peloton. But boy are they pricey...
Starting as short as 145mm, there is a 5mm jump up to the next size option, to 150mm, for the Gossamer chainset (priced at 178 euros). Also available are 155mm, 160mm and 167.5mm versions, alongside the original line up of 165mm, 170mm, 172.5mm and 175mm sizes. That is a huge nine different arm options so you can really dial your position and optimise power output.
FSA says this crank size “allows a ‘shorter’ movement of your leg by creating less turbulence and therefore more aerodynamics performance”.
It has been developed in response to feedback from FSA/Vision-sponsored professional triathletes, as pedalling with shorter cranks is said to be closer to the leg movements when running. “It creates less physical decompensation allowing the riders to face the last phase of the race in an optimal way", FSA says.
Shorter cranks have already been acknowledged to increase comfort thanks to the reduced range of motion at the knee, hips and lower back, and if previously restricted in these areas, this could in turn increase power output.
Fitting Shimano and Sram 10-11 speed systems, this anodized black aluminium crankset is available in 2x and 1x options, and both have a Q-factor of 145mm.
Among the other updates are slimmer versions of the FSA Energy alloy handlebar (104 euros), which will now be available in 360mm and 380mm options, and are said to be suitable for female and junior (under 18) cyclists.
These new super compact versions keep the 4 degree outward bend, 34mm ergonomic flat top and 110mm wide round centre section to make it easy to mount accessories, but come in slightly lighter at 255 grams (380mm).
Costing a whopping 629 euros, Vision’s full carbon extensions, the Metron TFE Pro Clip-on Extensions, are part of the 2021 line up after being developed with feedback from the likes of Primož Roglič, this year’s Vuelta a España winner.
Compatible with Metron TFA aerobars and the Trimax Carbon SI 013, these 360 gram bars (pair – 305mm) are reportedly 8% faster than the standard Vision extensions, and 9.4 seconds faster on a 40km time trial.
Vision’s speed extensions, which still boast a full carbon construction and clip onto an integrated system for optimal aerodynamics, come in at a 293 euros and are available in J-Bend and S-Bend versions.
