Are my chainrings shot?(4 posts)

Are my chainrings shot?ishmael

Ive replaced the chain and the cassette and Im getting an unpleasant grinding/clunking sound. It shifts fine but its really noisey, especially in the lower gears while climbing when I put a lot of pressure into it. Dont know how many miles its been but roughly 200 miles a week for a year and a half with the same chain. I had to replace the cassette because the new chain wouldnt work with it, could the rings be abused from the old chain too? I cant imagine anything else that could be the problem.
theyre campy 10speed, maybe too fragile nmishmael

if you are saying you put over 15,000 miles on your drive train without changing the chain, yes they are shot. Thats not terrible life. Your chain became stretched out long ago and damaged your cassette and chainrings. You may have gotten better life from your chain rings replacing your chain before it wore out but thats great life for a cassette. I usually get about 6,000 to 10,000 out of a Dura Ace cassette. Buy a Park chain checker and read the instructions on how to use it to properly maintain your drive train. LoL

I've heard when you get some parts replaced in your drivetrain it can be a good idea to replace everything at once as the parts tend to wear into each other. To some extent I bet this advice gets overblown, because I've replaced plenty of things without having any issues with other parts. I have however had one experience where both chainring and chain managed to last long enough for this to come up. I replaced the chain first and also got a grinding noise and the chain kept falling off the ring. I replaced the ring shortly after and everything else was alright.
