I have this on two different bikes, both with disk brakes, one as a front rack (fat bike with 26x4.0 tires), and the other as a rear. Mounting hardware is well thought, but doesn't include bolts if you'e using the plated steel bracket. A trip to the hardware store for some M6 bolts, washers, & nuts worked well. I've used these with panniers full of groceries, canned foods, 1 gallon jugs, and they hold up well.
