The Quill is our most innovative road rim to date. Utilizing design technology from our Aileron disc rim, we've evolved our most successful and proven A23 road rim and developed the machined Quill to be, stiffer, and wider than its predecessor. The Quill rim is 17.2% wider internally, 26.2% laterally stiffer, and 99.3% radially stiffer than the A23.* Featuring an outer width of 24.5mm and an internal width of 21.1mm, the Quill's voluminous width provides riders with substantial lateral stiffness even in lower spoke counts and increased ride quality and control. The 25.5mm depth, provides an aero profile giving it significant performance and durability gains over previous rim brake models. The Quill can easily be set up tubeless with the use of our 24mm wide Velotape. Tight tolerances require the use of a low profile rim tape like Velotape to avoid tire installation issues. Veloplugs are not recommended on Quill rims.
