This whole thread points out how much fun the 3-speed, or really the "sportster" series is, the mixing and matching and mis-matching that can go on to get a good ride.

Just today at lunch I was holding up wheels to frames and discovered that a set of 27 x 1 1/4 wheels from a Bridgestone 300 will fit great in my India Hercules frame, leading me to believe that it was originally built for 28" wheels. It only came with 26" wheels when it came to me.
