The HF-2 cranks are Promax’s top-of-the-line crank offering. Hollow-forged from 6061-T6 aluminum, both crank arms are hollow so they are super stiff, yet lightweight.
The crank arms spin on a beefy 24-millimeter spindle permanently fitted into the drive-side arm.
With a 104-millimeter BCD four-bolt spider, they come in a variety of beautiful anodized finishes.
Available in anodized red, blue, gold and black with laser-etched graphics in 170-, 175- and 180-millimeter lengths.
Bottom bracket sold separately.
Meets or exceeds ENBMX standards.
