Made by Enduro, this #6804 sealed cartridge bearing measures 20x32x7mm and is chrome for added durability. Sold as a pair of two. Replaces Stan's part numbers ZH0818 and ZH0819.
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.
