Description

The Onyx Helix front hub is arguably the highest quality hub on the planet.
Unique cut-outs in the hub shell are not only aesthetically pleasing but save weight without sacrificing strength. Making the Onyx Helix front hub the number one choice of the pros.

*Tightening axle bolts more than 12NM will void the warranty

Features

Cut-out shell saves weight. Cut-outs through the hub shell drop weight without giving away strength, and they look the part while doing it.
100mm BMX front spacing. Built to 100mm BMX front spacing, so it laces into a standard 20 inch front wheel.
20mm thru-bolt fitment. The Helix runs a 20mm thru-bolt setup, so it suits forks built around the larger front axle.
Torque axle bolts to 12NM. Onyx warn that tightening the axle bolts past 12NM voids the warranty, so a torque wrench is worth using.
Axle sold separately. The axle and thru bolt are not included, so order one to suit your forks if you do not already have it.

Specifications
