Warning about using I9 rear hubs – a never ending saga of breakage.. I went thru 4 Hydra hubs , they last about 400 miles with following things happening in random order:
1 – Axle crack because its designed to flex in order to get that engagement
2 – Bearing failure due to that flex axle
3- Drivering craks just like in the video
4- Pawls seats mushrooming and eventualli stripping the freehub

Mine has a few thousand miles on it and outside of a bearing replacement it’s been perfectly reliable.
Bummer you’ve had such issues.
I have two hydra hubs, one on a trail bike and one on an enduro bike. My trail bike hub had the pawl pocket stretch which caused pawls to chip, having to replace the freehub now at almost exactly 400 miles. My enduro bike hub has visible pawl pocket stretch but hasn’t started skipping yet, probably only a matter of time. A 2 year warranty seems pretty short for hubs. I think the next time I get new hubs, it will be with some other brand.
1/1’s on 3 of our bikes, including an emtb, and zero issues. I couldn’t find the reason to go for the hydra at more than double the cost without any benefits.
This is some excellent, well documented information. This is the best sort of thing for people to make informed purchasing decisions.
