Back in the day if yer bike came with Mafac brakes it also came with a little tool set maybe the size of a pack of regular cigs . That little tool kit & Crescent wrench were the only tools some bikes ever saw during their lifetime after getting bucked in the bike shop . A lot has changed in the bike world since I left it .

thanks

I don't know the specs on the gear you need but, there is a good chance is it a custom-size or profile.

I machined a custom Sturmey-Archer Hub Shell back in the day! I also produced for a local hardware store custom axle nuts for S-A hub Axles!
