180mm Bicycle Brake Caliper Adaptor
thingiverse
The standard type of adaptor to change your bicycle from a 160mm to a 180mm rotor. Mount with the thicker side further away from the axle. I used M6 x 30mm bolts, 35mm bolt might be better if threaded mounts are long enough. The "normal" version is based off of store-bought aluminum adaptor dimensions, the "extra room" one gives more space if the caliper is too big to fit in the standard adaptor.
