I see the 650 vs 700 debate still rages. I remember Fred DeLong writing about the advantages of 650B tires in Bicycling magazine back in the mid 1970's. To which someone responded that 650B's were fine for people who were more interested in trying to find parts than riding their bikes. Fortunately, it can be a real debate now. (For the record, we ride 700 x 32 on our Santana)
