With a redesigned axle, larger bearings, and improved seals, this hub keeps grit out and power in, mile after mile.

Who is this for?

This hub is for riders who demand race-ready durability on rugged terrain—trail, enduro, downhill riders, and e-bike enthusiasts who push power through rough trails and long days in the saddle.
