Helix shell

Description

The Onyx BMX front hub in the Helix shell, drilled 28 hole. It runs 100mm spacing with a 20mm thru-bolt axle, the fitment for forks made for the larger front axle.

This is the custom colour version, so you pick the finish when you order. Sold as a front hub on its own, not as a built wheel.

Features

28 hole drilling. Drilled 28 hole, so it laces to a 28 hole rim with spoke lengths worked out to match.
20mm thru-bolt front axle. Built around a 20mm thru-bolt, so it suits forks made for the bigger front axle.
100mm front spacing. Spaced at 100mm, so check the gap between your fork legs first.
Helix shell. The Helix shell version of the Onyx BMX front hub, rather than the solid shell.
Custom colour build. Listed as a custom colour hub, so you choose the finish to match the rest of the build.
