Upgrade your bike's drive system with a star ratchet hub manufactured by Wren Sports and designed to excel in high-torque situations with powerful mid-drive motor eBikes. Available in 32 holes and can be set up for 190mm or 197mm rear-ends.
What is a star ratchet hub?
A star ratchet hub is a robust and reliable hub design that distributes a load of your eBike's motor across 36 points of contact instead of the 4-6 points of contact on a pawl-based hub.
This addresses a common point of failure for many regular hubs where the pawls will break or strip the race in the hub causing the power to no longer be transferred to the rear wheel. The even power distribution between the star ratchet teeth ensures a smooth and reliable drivetrain.
No Tool Construction
The star ratchet hub can be assembled and disassembled with no tools, resulting in easy access to bearings, freehub body replacements, and configuration between 190m and 197mm.
|Cassette Compatibility||11 Speed|
Ottalaus replaced my OEM hub that failed after very little use with the Wren Star ratchet rear hub. Very happy with the performance! Looking forward to many winter miles ahead!
