Promax HF-2 BMX Cranksets 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. The HF-2 is available in anodized red, blue, gold, and black in 170, 175, and 180mm lengths. Now also available in 172.5 and 177.5mm lengths in black only.
