I am looking for the concave/ flat washer that goes on the front of the front mech braze on. The retaining bolt passes through this part, then the braze on then screws into the mech - perhaps with a flat washer too. Does anyone have a spare kicking around ? I want it for an Ultegra mech but reckon most parts will fit. Do you have an old knackered braze on front mech that you want to dispose of ?
