Topeak Super Tourist DX Disc Compatible with disc brake bikes. In my case, I installed it on a 27.5x2.6 MTB, and it barely fit. By "barely," I mean there was about 1.5cm of clearance between the underside of the rack and the tire. I used it six times for one-night camping trips. There are some scratches from pannier bags and some marks from leaning it against rocks. All the parts and the instruction manual are included, but please note that some of the washers and bolts for the eyelets are not original.
