Hi - new to forum and new to home mechanics so bear with me. I have an early stumpjumper m2 which I love. This bikes not the issue, the offending bike is a trek 6700 from I think around 2001. I bought it for £30 as parts but I can't bring myself to kill it (such a nice frame). So the chain/crank slips under pressure. I think it's the chain rings as they look terrible and the middle is buckled and will start with these. It has a bontrager comp crankset (4 bolt) square BB. I like the set so would like to keep if possible. Can I just replace rings, they are 44/32/22? If so any advice on this or recommendations on where to get rings, second hand looks like a lottery. Stu
