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 shell with a finely indexed freehub that ensures direct power transfer and a solid riding feel. With a Boost spacing of 12x148 mm and 28 spoke holes, it allows you to build a stiff, durable wheel for trail, all-mountain, and enduro riding.
Modern standard: Centerlock & Micro Spline
The hub uses a Centerlock disc brake mount, allowing for quick and clean disc changes and ensuring optimal compatibility with modern Shimano discs. The Shimano Micro Spline freehub body is designed for current 12-speed MTB cassettes and provides a secure, play-free connection under high loads on rough terrain.
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.
