I know most of you with MB do not use the skinny tires, but I have a lot of brand new tires to get your old 3,5,10spds, etc., bicycles back on the road. I repair a lot of local people's bikes & buy these in large quantities. These are the harder to find 27 x 1 1/4" tires, & 26 x 1 3/8" Schwinn type bike tires. $10ea + shipping. Tubes-$4.
