By reshaping the crank arms with a narrower profile and smoothing out transitions, OVERFAST have been able to cut down the resistance created at the heart of the drivetrain.

In wind tunnel testing aero cranksets have shown savings of up to 6 watts at 45 km/h, depending on rider position and setup.

That might sound modest, but across a 40 km time trial those watts translate into seconds gained without any additional effort.

Over the course of a long road race, it can mean conserving enough energy to make a decisive move when it matters most.
