i have some hayes hfx-mag xc brakes, used about a week, that i want to sell off my xl kona coiler (with rotors). i looked in the classifieds to get an idea of what to ask, but all the hayes hydraulic brakes were sold. what are people paying for these things? what should i ask when i place my ad. i also have a pair that's about a year old, and needs a new front rotor and pads. i'd probably trade those for 2 cases of sierra nevada if anyone is passing through ely on the way to moab (you can get sierra at the costco in reno for about $20/case).
