Description

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. The crank arms spin on a beefy 30mm spindle permanently fitted into the drive-side arm. 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)
  • 30mm spindle provides increased stiffness and efficient power transfer
  • Pedal washers included and required
  • Bottom bracket sold separately
