A black handlebar clamp for a Promax HF-3 Crank Set.

A lightweight bicycle handlebar with a Promax HF-3 Crank Set attached to it.

Description

Promax recently released the HF-3 Crank Set in 2023 with a super strong 30mm spindle! These aluminium cranks are hollow-forged from 6061-T6 aluminum, leading to a lightweight crankset. This combination is both light and stiff and backed with Promax's reputation for manufacturing affordable AND durable BMX race components.
A unique feature is that these cranks offer a direct-mount sprocket compatibility for additional weight savings, or run them with the included 104 BCD spider adapter. we would personally run them with the spider to make gear changes easier.Construction and features:

Features

Stiff 30mm spindle. The oversize 30mm spindle adds stiffness and transfers power efficiently instead of losing it to flex.
Hollow forged arms. Hollow forged and CNC machined 6061-T6 aluminium arms keep the crankset light, strong and stiff.
Direct mount or spider. Run a SRAM 3-Bolt direct mount chainring to save weight, or fit the included 104 BCD spider to make gear changes easier.
Single speed 3/32 drivetrain. Built for a single speed 3/32" chain and 104 BCD chainrings, the standard race combination.
Supplied in 175mm. One crank length at 820g with the spider fitted, and the required pedal washers are in the box.
