Disassemble & Re-assemble Vintage Suntour Rear Derailleur

Posted by on in Derailleurs


I show how to take apart, clean, lube and put back together a vintage Suntour rear derailleur. Unlike other derailleurs, to remove the pulleys, or at least the guide (jockey) pulley, you have to take these old Suntours apart. The derailleur in the video is a Suntour Vx GT. There are a couple dozen models of these vintage Suntour derailleurs that also need to be disassembled like this. They might be slightly different, but the process is pretty much the same.
