    650B wheels

    Just wondering what people's opinions of this size are. I think, at least in theory, they're great. I haven't ridden them yet though. Anyone have any reason not like them? Think they'll be around in 3 or 5 years?

    I have about 50,000 miles of experience with 650B wheels. They were on a custom built touring bike of mine built in the mid 70's. Imagine a tandem but without space for a second rider.

    One of the biggest disadvantages was the lack of availability of the tires. Usually I ordered 650B tires in quantity, but while touring availability presented more of a problem.

    My bike could accommodate three different widths and almost all of the time I used the narrowest and ran them at 90 psi. Blow outs were a problem as the tires aged, but normally I got a few thousands miles out of a rear tire.
