Upgrade Stan's Neo & Neo Ultimate Hubs

with the E-Sync Freehub

We designed our E-Sync hubs by building on what we've learned from our previous generation of Neo & Neo Ultimate hubs. Since E-Sync uses a similar hub shell design, the improved freehub driver and strengthened Chromoly axle is backward compatible with existing Neo and Neo Ultimate hubs.

  • New pawl angle and longer pawl shape, increasing torque load
  • Chromoly steel axles, strengthening the overall system
  • Double row bearings, adding stiffness and aligning pawls
  • Improved freehub seal, protecting internals against dirt and weather
