Good comments in this thread about the Suntour V GT - I try to keep one or two always on hand simply because they keep on working and working and working. Although I've seen a pretty fair number of cracked and Prestige RDs, I've never had one actually break on me - and I rather like the way they shift on a five speed rear. On the other hand, I have had the Delrin crack and snap under under riding torque on a Simplex FD. No harm done other than the soiling of my britches because it scared the living hell out of me.
