Wind-tunnel validated.
Road tuned.
CFD development and A2 Wind Tunnel testing shaped Polaris for speed, stability, and predictable handling across real yaw angles.
Superior Aerodynamics
Through careful optimization of the rim shape and rim-tire interface via thousands of hours of Computational Fluid Dynamics simulations, as well as wind tunnel testing at the A2 Wind Tunnel in North Carolina, USA, we were able to design a series of rims that works admirably fast. During testing, our rims matched favorably with class leading wheels - our Polaris 56 in particular is faster than a Zipp 454 NSW and remains aerodynamic to a greater wind angle.
Calming Stability
Blowing away the common wisdom that deep-section wheels are hard to handle, the Polaris 69mm handles crosswinds with aplomb. Designed with a priority on handling transient gusts, Polaris minimizes steering torque, while maintaining torque linearity to a greater wind angle. A linear response means that steering is more predictable with less twitching or jerking during sudden gusts, while a lower steering moment means less effort spent keeping the bike moving straight.
The Polaris 42mm features a near-immunity to crosswinds, with a near-zero steering moment that provides exceptionally good response in bad weather.
The Polaris 56mm easily matches a Zipp 454 NSW in crosswind performance, while maintaining handling over a larger range of angles (17 deg) than the Zipp 454 (16 deg) before stalling.
