Unlike other brands that slap their logos onto open mould products, we meticulously design Polaris to exacting standards - from Finite Element Analysis to Computational Fluid Dynamics, our products use state-of-the-art simulation and optimization techniques to bring the highest performance and user experience to the rider. It's not easy - we are the only company in Singapore that does carbon wheel design, but our custom rim designs attain a performance unreachable with open-mould rims.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSUPERIOR AERODYNAMICS\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThrough 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 56SL in particular is faster than a Zipp 454 NSW and remains aerodynamic to a greater wind angle.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCALMING STABILITY\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eDesigned 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 42SL maintains a near-immunity to crosswinds, a testament to the extensive CFD simulation and wind tunnel validation performed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFORTIFIED SPEED\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAn updated rim layup gives a 33% improvement in impact strength from 90J -\u0026gt; 120J, 3x the UCI requirement.
