Ordered this and the 180 adapter for my 22'' gravity monster bullseye fatbike because I upgraded the brakes. I went with the SLXm7000 hydros and slx rotors. Because I had all shimano components they all bolted up together perfectly. This bikes stops so fast it scares me...and I'm 6'6'' 250lbs which usually means my momentum pushes me through the brakes. Treefort ordered these adapters for me over the phone and had them ready for pickup in less than two days.
