The concept of Hollowtech II technology is focused on producing a superior crankset that will maximise a rider's power transfer. The rigidity of the crankset ensures pedalling efficiency while its weight, a key element of the crankset, you want light, aids in cycling longer distances over which the rider needs to pedal more.
