Good point. This is a grab-n-go ride anywhere hackback. It would have been more cost effective to replace it with another cheap MTB or hybrid than to bother with building wheels. I picked up a nice set of 700c rims for $75 and fitted $8.00 tires. The Schwinn works better than it should.

I loved the 650b concept. Cost is the biggest factor. Wish I could find a set of 650b disc mountain bike rims for my Nashbar bike. They'd fit with 40 Panaracers.
