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. The polished finish gives a nice classic look suitable to classic as well as more recent bikes. 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.
