I'm being a bit vague, but I'm looking for a quality front/rear set of V-brakes with levers. I've got XTR brakes on another bike, and they've been great, so something similar would be good. I've been having a look around, and would be interested in XTR, Avids, Pauls etc. I'd also consider canti's if they can use cartridge pads, or even Maguras.
