The Quill is our most innovative road rim to date -- an evolution of our proven A23 that borrows design technology from our Aileron disc platform. Wider, stiffer, and more aerodynamic than the A23 that came before it, the Quill's 21.1mm internal width delivers substantial lateral stiffness even at lower spoke counts, along with better ride quality and control. A machined-sidewall, tubeless-ready rim for road riders who want a real step forward without leaving rim brakes behind. Built with Velocity Standard hubs and Sapim Leader spokes. Each Velocity wheel includes our best "rim tape" solution standard. Velotape for tubeless models, Veloplugs for non-tubeless models.
