Hi all. I am new to trials and are in the process of building a bike. I've just bought a pair of Magura rim brakes, (retro yellow). I know it's too late to change my mind now but I was just wondering why you guys prefer these brakes to a pair of the many disk brakes available. I can't get a real answer from any of my mates. Also why is it that some prefer to run a disk on the front? Any info would be useful. Thanks, Rob
