This heavy-duty pawl and spring kit fits all E-sync freehubs. The kit includes four pawls and four pawl springs. This pawl and spring kit is compatible with all E-sync hubs. Not compatible with M-pulse, Neo, or Neo Ultimate freehubs, but can be used in conjunction with E-sync freehub as a retrofit upgrade to Neo and Neo Ultimate 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.
