105 Crank Set

The Hollowtech II crank and bottom bracket combines race-proven hollow forging technology with the integrated crankset & bottom bracket. Weight is reduced while rigidity & power transfer is radically increased.

In addition to Hollowtech II integrated design; the crank arms are hollow which provide amazing strength and rigidity at a light weight.
