I have one lightweight custom 650b machine shod with the Hutchinson Confrérie des 650B, which measure out at 33mm wide on Velocity A23 rims. I think they ride very nicely - I'm fairly light at 65kg, and I run them at 40psi front and 60psi rear. They also roll out pretty well - I take that bike on on some of the bunch training rides with the local racing cyclists. I'm running them tubeless on the A23s.
You can buy them for under $30/tyre from XXCycle in France: https://www.xxcycle.com/tyre-hutchinson-confrerie-des-650b-275-650-b-ts,,en.php I also have other 650b machines using the Hetre 650Bx42mm tyres and Compass 650Bx48mm. Although there's undoubtedly more shock absorption with the fatter tyres, for rides that are largely on sealed roads I prefer the Hutchinson tyres. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
