Sawtooth accomplishes this by inducing small sheet vortices that shed at a low magnitude, but at a higher natural frequency, thus decreasing the laminar bubble effect on the aerodynamically shielded side of the rim's profile to further reduce high yaw drag and improve crosswind stability BuyZipp Wheels & Tyresfrom Chain Reaction Cycles, the World's Largest Online Bike Store.
