The revoultionary rear adaptor that converts Aluminium none disc frames into a disc frame. MBUK review 4/5;For this to work with your frame you need to have a Alluminum frame with a flat style dropout on both sides which is normally about 8mm thick, theA2Z adaptor then opens up and sandwiches over your frame and creates an International mount - No drilling or bolting into your frame is needed.;It does not affect your hub or Q/R in anyway. Not Compatible with Hope BigUn Hubs.;It will only work with Vertical dropouts;Not compatible with Specialized Frames where the dropout is slightly angled backwards
