I notice most of you have nice wide tires on your rides. So are you using your vintage mountain bike to ride dirt, trails and the like or more for just cruising around asphalt, streets? I had these on my Sekai for awhile - they look awesome but they're so wide. The DMR SuperMoto black/skinwall are 26 x 2.2". They looked huge compared to the rest of the bike, so I took them off for some Continental Travel Contact 26 x 1.75" tires.
Here are the SuperMotos:
