Stans NoTubes - E-Sync OS/Neo End Caps 20mm Boost E52/E52

This pair of front-end caps is designed to fit 6-bolt E-sync OS and Neo OS hubs when used with 20mm Boost axles. The end caps feature a low-friction U-cup seal that snaps into place and stays secure even when your wheel is removed from your bike. DH forks went through a change in disc brake caliper position in 2019, creating a new 20mm Boost fork spacing that differs slightly from previous 20mm designs.
Not compatible with Centerlock or non-OS hubs. Not compatible with M-pulse hubs.
