I have a Truvativ GXP2 2.2 chainset on my 2010 spesh pitch pro. the big ring (36t) is worn and the chain slipping. looking at different chainrings on CRC etc and I don't know whether I need a truvativ, a SRAM or another brand? Any ideas? Would say a superstar or other brand fit?

Have a look on the old rings and see what the bolt centre diameter (bcd) is?
You should then know what will fit. Or you could measure this?
hope that helps

Charlie The Bikemonger has a very handy chart to convert the measurement between bolt holes to BCD.

You could be even nicer and buy a chainring from him too. 🙂
