What bike(s) have you converted to 650B? What tires fit?
Make | Model | Year (or era)/ serial number/ distinguishing feature(s)/ color | Frame Size | Largest 650B tire that fit (stock) | Try anything that didn’t fit? | Brakes used to convert | Other comments | Contributor |
Centurion | Turbo | 1983 | 58cm | Col de la Vie 38mm | fenders | Tektro R559 | Rory! | |
Katakura | Silk | Full chrome, ca. 1984 | 61cm CTC | 38mm with fenders | none | Tektro R559 | Easiest conversion I’ve ever done…this bike fit the tires/wheels almost as though it were designed to do so. Fork was medium trail though. | Azorch |
Nishiki | Comp II | 1986 | 56cm | 42mm | Tektro R559 | Bruce | ||
Torelli | from Cinelli Corsa factory | 1983-4 | 57cm | 38mm | Too tight to safely run 42s | Tektro R559 | Bruce | |
Trek | 420 | 1989 | 58cm | 42mm | fenders | Tektro R559 (maxed out in back) | Here is a slightly older one that fits Hetres & fenders: http://brazenbicycles.com/Trek-650b-Town-and-Country
Also this looks like a 1986 400: http://brazenbicycles.com/Trek-400-650b-Sport-Touring |

Nishiki Comp II 1986 – 56cm – 38mm Col de la Vie, 38mm Soma B Side fit and 42mm Hetre 42mm fit. Tektro R559 brakes.
Torelli Columbus lugged steel frame, possibly from Cinelli Corsa factory, approx 1983-4 – 57cm – 38mm Col de la Vie and Soma B Side fit, 42mm Hetre 42mm also fit, but without enough clearance to be really safe. Tektro R559 brakes.
