This looks like the one i have got (from what i remember when i have removed my crank before). I guess when you have an expressive bike, everything is expensive for it =(

Ceramic on a factory bike, damn... is it not covered by warranty ?? LOL

I would of though they would have said its wear and tear and not a warranty issue, as i said, it's only from what i rememeber. Not doing anything tonight so may wip the crank off tonight and check to see if theres any numbers for refences.

Good news, it says its an Truvatic GXP (not super duper £150 joby but £30) on it so would of thought i would need
