Above we have a driveway pic of the latest, and GREATEST, 650b option, the Soma New XPress 650b. RBW has a nice description and comparison to other 650b offerings. They're not mounted, but if I can talk Dave into a Sunday morning ride we'll test them out. Marketing suggests a tire about the same size as the CdlVs (wider than the Cypres'), but with a tough, no-flat casing. I've yet to have a flat on the CdlVs', but they're hell to mount, so maybe these will be a bit better, although I've heard that the first run of wheels that came with the Bleriot offering had a diameter slightly too small, rendering loose tires even looser.
Happy Hour Brew Cruise tonight and a busy day tomorrow, but it's the weekend. Vamos!
