How many miles on those rings and cogs? I've got 10K+ miles on the single 46 t Cyclotourist (old mfr) ring and almost that much on the 15 t Dura Ace track cog; the cog is fine, the ring is showing the beginning of "hook" where the backside of the troughs wears from the rollers. (No sign of deterioration in performance, though. I check my chains regularly and have changed that on this bike at least 3 times; how long do *you* get between that 1/8" stretch? -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
