I need to design and fabricate (cnc mill) custom dropouts for a bamboo bicycle from a plate of 6061 aluminum, but i do not know any of the industry standards for derailleur hanger locations, or disc brake tab locations relative to the location of the rear axle in the dropout. The bike will be using Avid mechanical disc brakes and a 9spd Shimano Deora derailleur, and the dropouts will have a standard 135mm spacing for the rear wheel. If anyone can help me find a general set of dimensions to go from for the derailleur hanger and disc brake tab locations so that I can fabricate these components and continue my construction, I would be extremely grateful!
