Hey,

so right now I am running an 8 speed casette with a triple crankset. The crankset is a Truvativ ISOflow Road with 52-42-30T and is ridiculously cheap and is bent up. I want to upgrade my crankset but was wondering if it would be a problem to put a 9sp or 10sp crankset on with an 8 speed cassette or does it matter? I was looking for another reasonably priced triple crankset since I am still a novice rider. I was also wondering if it was ok to run a 9 or 10 spd derailleur on an 8 spd cassette? Any help would be great ?

Thanks,
Ryan

Doing that normally does not cause any problems.

Yes you can use a 9 or 10 speed crankset with a 8 speed cassette. the thickness of chains has changed with more gears skinnier so as long as your current chain meshes right your all set

Good decision on changing that truvative crank.I had one stock with my Scott,and it wasn't good.You can get a 10 speed 105 5600 pretty cheap
