I haven’t had a problem besides some dropouts which have been fixed ( for the most part) since the new update. The dropouts haven’t reflected negatively, maybe 3 dropouts on a 2 hour ride. I’ve also banged them a few times really hard on some stumps, ridden them through chunky rock gravel sections that hit every part of the bike. Im happy with my purchase; I’m just under 2,000 miles of use with my rally xc200s.
