Key Features:

Hollow outer chainring, giving vast improvements in rigidity
The hollow outer chainring has essentially removed outer chainring flex, hugely improving shift performance making it precise even under high load
These industry leading HollowTech II 4 arm cold forged hollow crank arms have been evolved to increase rigidity and improve strength
The teeth have been developed to work only in conjunction with the 11-speed chains for improved contact providing more efficiency and improved power transfer
There is a wide range of chainring ratios and crank arm lengths available enabling customisation for all riders and racing disciplines
HollowTech II integrated bottom bracket design uses a wider bearing placement and larger axle diameter for increased stiffness and efficiency
Bottom bracket seal design has a minimal bearing interface gives superbly smooth rolling and increased durability
Weight 609 grams (50-34T)
