Our original Neo hub has evolved to be stronger and more reliable than ever. The additional stress of larger cassette cogs, more capable bikes, and even more challenging trails led us to create the Neo with Speedsync.

This freehub is a direct replacement for your Neo Ultimate hub, and includes the required drive-side specific endcap, pawls, springs, pawl retaining ring, and freehub spacer. Bearings are pre-installed. Compatible with only Shimano Micro Spline cassettes. Not compatible with Shimano HG or SRAM XD/XDR cassettes.
