Features a disc specific elliptical profile designed with aerodynamics and weight as key factors. Specifically tuned to be aerodynamically paired with 23-28c road tires, though a 20mm inner width compliments even the most voluminous gravel and cross tires. Tubeless ready using 24mm Velotape. Tight tolerances require the use of a low profile rim tape like Velotape to avoid tire installation issues. Veloplugs are not recommended on Aileron rims.
