With a wider footprint, the A23 allows for a more aerodynamic rim/tire combination when paired with a 23c tire. 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. A tubeless ready design makes this rim ideal for road and cyclocross applications. Tight tolerances require the use of a low profile rim tape like Velotape to avoid tire installation issues. Veloplugs are not recommended on A23 or A23 OC rims. Based on the proven Aerohead rim, but with a wider footprint Allows for a more aerodynamic wheel when paired with a 23c tire Gives a tubular ride quality with the convenience of clinchers Ideal for road and cyclocross 23mm wide and 19.5mm deep, ERD 601, 450g
