I can't imagine how anything in there could cause that groove. The pawls can't move any direction other than in/out. MAYBE if some kind of debris got in there, or if you chipped a tooth on a pawl or the ratchet ring, perhaps that was smashed into the hub body while under load. Any sign of broken teeth anywhere?? Very curious.
Nice freehub design though. It's very similar to Industry Nine, which Paul uses in their RHUBs. 6 pawls, each with multiple points of engagement, makes for a buzzy hub but very quick engagement and a nice distribution of the load. Not sure if you can do this or not, but Industry Nine says you can remove three of the six pawls if you want, which makes it quieter and less drag, while sacrificing the 'immediate' engagement a bit. I personally have no idea why anyone would want to do that, but to each their own. On Thursday, March 24, 2016 at 8:45:17 AM UTC-5, William R. wrote: > > Hi Bill.
