ISO 584 650b - 27.5"

This size is mainly seen on older French touring bikes and tandems and some Rivendell models.

An increasingly popular choice for conversion of 700c bikes.

650B size allows for wider tires and more clearance for fenders.

The recent 27.5" (MTB) size is the same diameter, but rims and tires under this designation are usually wider. 

Velocity A23 584 mm (650B) Rim 36 holes  Silver
$69.95
With a wider footprint, the A23 allows for a more aerodynamic rim/tire combination. The tire profile mimics the characteristics of a tubular, gaining increased control and lower rolling resistance without the inconvenience of tubular glue or the dangers of irreparable roadside mechanicals. Light in weight and tubeless-compatible, the A23 is an extremely versatile rim with a classic look. The A23 O/C rim is the off center version of the popular A23. The offset is 3.5mm, and the off center design allows for dramatically improved spoke tension on a dished rear wheel. Tight tolerances require the use of a low profile rim tape like Velotape or Stan's Tubeless tape to avoid tire installation issues, even when using clincher tires. Veloplugs are not recommended on A23 or A23 OC rims.
