Description

The HF-3 cranks are Promax’s latest top-of-the-line aluminum crank offering. Hollow-forged from 6061-T6 aluminum, these hollow crank arms are as stiff as they are light!

The crank arms spin on a beefy 30mm spindle permanently fitted into the drive-side arm. The oversized 30mm spindle results in even more power transfer ensuring every ounce of torque gets into the drivetrain for better launch.

Removable Spider allows for the use of Direct mount Chainrings for even more weight savings. Or use the included spider to mount traditional 4-bolt 104 BCD chainrings.

  • CNC-machined 6061-T6 aluminum crank arms are lightweight, strong, and stiff
  • Designed and optimized for chainrings and spiders with SRAMs 4-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
