Our MT series hubs are our flagship mountain bike hub range. The MT series encompass everything we feel hubs for mountain biking should offer.Durability, modularity and light weights make the MT Series a simple choice.Suited best to XC, trail and enduro bikes alike, the MT Supadrive hub offers a 120 point near instant engagement with the ability to withstand substantial torque loads, such as those found with wide range cassettes. With multiple World Championship titles across a range of disciplines the Supadrive system is tried and tested to the very highest level and is our most advanced and reliable drive system to date.Wide spoke flanges, sealed cartridge bearings and a Cr-Mo tube axle in the MT Supadrive hub ensure longevity.Designed to be run with mountain bike gearing, the MT Supadrive hub features an XD driver or alternatively a MTB width HG freehub.
