The crankset on my bike needs replacing as the outer chainring in slightly bent causing the chain to rub on the FD.
The bike is 8 speed Sora with a triple crankset (Shimano FC 3303 I think).
Does anyone know if i need to replace it with a 8 speed specific crankset or will a 9 or 10 speed suffice. I'm not too sure a 10 speed chainset with cope with the 8 speed chain (I presume the chain width is wider that a 9 or 10 speed chain), therefore this may cause problems with changing between chainrings.
As it for the Commuter bike, I don't want to spend a fortune.. (PS the current BB is Square Taper).
thanks in advance

Re: Replacing Sora Triple Crankset - 8 Speed
How "bent" is bent.?
I would see if it can be straightened with judicious use of force. Block of wood and hammer or use a vice.
You could also just fit a new chainring or change the whole unit for another make.
Perhaps one of Spa's :-

If changing the whole chainset then just check that your bottom bracket length is suitable.
P.S. I wouldn't consider a 10 speed chainset and the cost will be higher anyway.

You'll never know if you don't try it.

The outer chainring should unbolt and be replacable. Why do you think you need a whole chainset?
