Front hub adapter E-Sync OS / Neo OS Boots

This pair of front caps is designed to fit E-sync OS and Neo OS hubs with 6 bolts when used with 20 mm Boost axles. The caps feature a low-friction U-seal that snaps into place and stays secure even when your wheel is removed from your bike. DH forks underwent a change in the position of the disc brake caliper in 2019, creating a new 20 mm Boost fork spacing that is slightly different from previous 20 mm designs. More information on the difference between 20 mm and 20 mm Boost can be found here. Not compatible with Centerlock hubs or non-OS hubs. Not compatible with M-pulse hubs.
