I am thinking about a Christmas present to myself, and upgrading my Trek 6500 MTB (2007 model with V brakes) to hydraulic discs. The bike comes disc conversion ready with mounts on the frame/forks/hubs.
Having looked at various brake systems, the best VFM I can find is the Shimano SLX M666 system, with Shimano XT rotors. But what size rotors do I need? There is a choice of 160, 180 or 203 mm. Would I be correct in thinking 180mm on the front, and 160mm on the rear? Cannot find anything to tell me for sure!
