This crankset has been designed taking in consideration all parameters of pedaling. As the stress is maximum close to the axle and lower when you go the pedal, the crankset section has been especially designed that way. The consequence is an optimisation of the energy transmission. HR Carbon. Allows a high rigidity and gives a very high tech LOOK. Chainring compatibility: 130 mm (Shimano 39T/53T). Weight:449g without rings. Octalink Compatible.
