Ah, truvativ square taper, should read the post properly - it's early...
Still picture would help as we have a lot of LH Crank arms so could use an alternative to Truvativ if 170mm and the Hole matches up, what bike is it?
Diamondback Quantum - bought in dec from a chap who repairs bikes off chatsworth road - don't think i will be buying from him again.
Chain set is Truvativ x-flow.
If you can help that would be shweet.
