Agree on it being more difficult. All depends what will be permitted. I don't think welding brackets to the rear axle would be a problem, but because the front is a forging, they may not like that, but need to confirm. I may have to keep the original mounting if I decide to keep the mechanical brakes, as it seems the spring mounting, wishbone mounting, and mechanical brake lever are all combined, plus it is outside my intended frame width. Simplest is just to drill a hole and install a tee type fitting from Posies or other. Some rather interesting designs out there, and this is what I like as there is just not one solution. My original setup. Simple solution. Tougher solution.
