HF-3 cranks are Promax’s top-of-the-line aluminum crank offering. Hollow-forged from 6061-T6 aluminum, both crank arms are hollow so they are super stiff, yet lightweight.

These cranks offer direct-mount sprocket compatibility for additional weight savings, or run them with the included 104 BCD spider adapter.
- CNC machined 6061-T6 aluminum crank arms are lightweight, strong, and stiff
- Designed and optimized for chainrings and spiders with SRAM's 3-Bolt mount style
- Includes 4-bolt, 104 BCD spider/adapter (Not compatible with CK-1 crank spider/adapter)
