Industry Nine 1/1 Mountain Classic rear hub Boost CL

The Industry Nine 1/1 Mountain Classic rear hub brings precise power transmission, rich sound and durable performance to your trail or enduro bike and, thanks to Boost standard and Centerlock mount, is the perfect basis for a high-quality rear wheel with Shimano Micro Spline cassette.

Precision and driving power off-road

The 1/1 Mountain Classic rear hub was developed for demanding mountain biking and combines a robust hub housing with a finely engaging freewheel that ensures direct propulsion and a smooth ride. With a Boost installation dimension of 12×148 mm and 28 spoke holes, a stiff, resilient wheel can be built for trail, all-mountain and enduro.

Modern standard: Centerlock & Micro Spline

The hub uses a Centerlock brake rotor mount, which enables fast, clean rotor changes and harmonizes perfectly with modern Shimano rotors. The Shimano Micro Spline freehub body is designed for current 12-speed MTB cassettes and offers a secure, backlash-free connection under heavy off-road loads.

Durability and ease of maintenance

A precisely machined aluminum housing, high-quality bearings, and an end cap system designed for easy maintenance ensure that the hub runs reliably even in bad weather, on bike park days, and on long Alpine crossing tours. The design prioritizes high stiffness and durability, so even powerful riders and aggressive riding styles are reliably handled.
