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. The MT Front hub is our staple front mountain bike hub. From XC to DH the MT Front hubs have it covered. The MT Front hubs’ super wide flange spacing and sealed cartridge bearings ensure durability. Want to fit a Boost front fork but don't want to change your hub? Now you can, using our Front Boost Adaptor Kit - Part No. HUHAZM6FBK. Simply replace your existing end caps with the ones supplied in this kit, bolt on the disc spacer and you're good to go!
