Review on Stans Freehub Body Durasync 6 Pawl by Bennie Wilks

This is compatible with other Stans hubs, please copy and paste from Stans website. The original Neo hub is stronger and more reliable than ever. The added stress of bigger cassette gears, stronger bikes and even tougher trails led us to build the Neo with Durasync. This hub is a direct replacement for the Neo hub and includes pawls, springs, pawl retainer ring, red hub spacer and spacer for 9 and 10 speed cassettes. The bearings are pre-assembled. The hub is splined to accept any standard Shimano-style cassette. It is not compatible with SRAM XD cassettes.
