I am currently "down for repairs" waiting for a wound to heal after surgery, and thought I might get around to doing some maintenance on the bike. I haven't replaced either cable in years, and figure it might be a good time to do so while I am off the bike. I would like some suggestions on what sort of cables/housings to get and if there are any all in one kits (has housings and cables for both brakes and shifters) that are any good. I am on a 9sp shimano drive train.
