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. These end caps are compatible with both Boost 110mm and older 100mm axle spacing. Fits 6-bolt E-sync, Neo, and Neo Ultimate front hubs. Not compatible with Centerlock or OS versions of E-sync, Neo, or Neo Ultimate hubs. Not compatible with M-pulse hubs.
E-sync hubs are built to last, including under the higher torque and weight of eBikes. A 6066 alloy shell, heat-treated steel ratchet ring, reinforced pawls, and full Enduro bearings rovide brute strength, while 8.18° engagement provides the speed.
