I've got a 1980 Puch Magnum II that I built up 10 years ago and have just started riding again. It rips, with the Gila Kit, Mikuni 24mm, Destroyer pipe, etc. She does about 50-55 now and it takes a little while to slow down! I've got the original Mike Thomas Disc up front and upgraded (many years but only about 20 miles ago) rear drum shoes, and was wondering if anyone has done a rear brake disc? I see most lightweight mountain bikes have them these days so it makes sense they would be a lot better than what I have now.
Happy to have the ped ripping around again but want to be able to stop on a dime. Anybody build or have seen rear discs on a Magnum?
