A GuestInstalled these 2 weeks ago to replace XTR rings that were on my older S-works racer. They have been solid, just got back from 24 hours at old pueblo & rode these hard with no complaints. Trail conditions were challenging, very sloppy for a few laps, but these rings shifted fine even covered with lots of mud & wet decomposed granite gritty stuff.
Oh yeah, Tree Fort bikes had the best prics on these as well!!
