Like many, I bought this to remedy the slow engagement of the stock TR wheelset freehub, and it is a big improvement.
In the past, these freehubs have had a well-documented history of failure. Hopefully they've fixed that. Time will tell.
No instructions included, and some documentation would be helpful. It comes with a bearing shield, seal, and spacer that sits between the freehub bearing and hub body bearing. The spacer is thicker than the original TR spacer and you have to replace the old one with the new one or the freehub won't turn once you tighten the axle. The seal fits around the freehub body, but it wouldn't work with my TR hub, so either I'm trying to install it wrong, or it's not meant for use with the TR hub (I assume the latter, as the stock freehub didn't have it). Again, some documentation would be nice.

I bought a set of Reynolds TR 309/297 XC wheels and needed to swap the driver body to Microspline. I didn't realize this was the 6-pawl version, which doubles engagement over the stock (3-pawl) arrangement that came with the wheels. Was super easy to install too.
Excellent system, easy to install and replace the Normal hub with this 6-pawl version. Good price, competitive value. Highly recommend.
Replaced the standard one that came with my bike, this is way quicker engagement giving the bike a much more responsive feel. Super easy to install to, just need to remove and replace the cassette.
Wonderful quality and fast shipping. If Instructions was included it would have been nicer.
