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 Durasync.
This freehub is a direct replacement for your Neo hub, and includes pawls, springs, pawl retaining ring, red freehub spacer, and spacer for 9 and 10-speed cassettes. Bearings are pre-installed. The freehub is splined to accept any traditional Shimano style cassettes. It is not compatible with SRAM XD style cassettes.
