With specs matching the their competition in this sector, the HF-2s are aimed at riders who are looking for a crank set that can take on the big side of the track and the gaps that come with that territory, and at riders who can throw down the big power numbers. 

Hollow-forged from 6061-T6 aluminium, both crank arms are hollow so they are super stiff, yet lightweight. The crank arms spin on a beefy 24 millimetre spindle permanently fitted into the drive-side arm.
