Hi guys, I hope you can help. I have a 2012 Flash and would like to gradually swap out Sram components for XTR, I just think it is better engineered. I have ditched the XO brakes - they were hopeless and now looking to change out the XO front deraileur for an XTR equivalent which poses a couple of questions. Which model XTR FD would I need and do I need any other bits to make it work? I hand Sram XO chainrings, will these be fine with XTR and should I also go a shimano chain while I am at it or is the standard issue OK? Now if only Shimano did a BB30 crank I would be laughing!
