No I'm not a fan at using a disk on my trials bike! I was doing this sketch gap, and when I landed at the other side, I felt my brake go all funny, like it had burst, but it hadnt, when I looked down, my pistons were facing the oppoisite direction, I was ment to use a brake booster but I had spaned it a few weeks before! The maggie mount felt as if it wrapped itself around the frame! lol Its cool!
