Jex Manufacturing's Float-Lock® sprocket hub is a simple, lightweight, 2 piece design that allows the rear sprocket to float and oscillate on the rear axle. Lead, wedge, and chassis flex can cause misalignment of the chain from the clutch to the rear sprocket. The Float-Lock sprocket hub helps to compensate for this misalignment by reducing power robbing chain bind. This allows more power to transfer to the ground.
The patented, 2 piece, interlocking design keeps installation and maintenance simple and straight forward. No screws, ball bearings, gaskets or tiny parts and pieces to break, loose, or replace.
