Our H3 wheels offer full on aero performance in any conditions. The key to the wide range of performance is the combination of a 55mm deep rim section, the airfoil section spokes and the smooth transitions between the two. The 55mm deep rim keeps drag low at shallow yaw angles. When the yaw angle goes past 15° the aero spokes work to keep the wheel from stalling, and drag stays flat. The optimum wind angle for the H3 is an amazing 17.5°. H3 clinchers are made with a light and durable alloy rim cap. Tubulars are offered in either alloy rim cap or all carbon.
