SUB-1KG POWERHOUSE
The Polaris 42SL and 56SL weigh in at 974g and 1070g respectively, and are packed with the latest in carbon rim innovation to give them an incredible 120kg rider limit with a 120j impact rating for durability.


LIGHTNESS. DISTILLED.
Hyper-intricate layup with liberal use of quality Toray T800/T1000/M40J carbon fibers result in a 70g weight reduction per set of rims.
Enjoy more responsiveness during sprints and attacks with lower rotational inertia where it counts the most.
AERO DONE RIGHT.
The performance and stability of Polaris SL stems from our deep experience in engineering and design.
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.



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 56SL in particular is faster than a Zipp 454 NSW and remains aerodynamic to a greater wind angle.
Calming Stability
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 42SL features a near-immunity to crosswinds, with a near-zero steering moment that provides exceptionally good response in bad weather.
The Polaris 56SL 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.

EXCEPTIONAL QUALITY
Manufactured with state-of-the-art techniques for quality and lightness, Polaris rims have stood up to the scrutiny of ultrasonic inspections, borescope inspections, and digital microscopy with zero cracks, delaminations, or structural issues detected..

Ride hard, race harder - we've got your back with our lifetime warranty against manufacturing defects*. Even better, all Polaris wheels come with a crash replacement guarantee. If you manage to damage your product while riding, racing, or even during an accident, we will replace or repair Polaris for you at zero parts cost**.
*This warranty is valid for the original owner. It covers the rims, spokes, and hubs, but does not cover damage due to wear and tear (e.g. bearings, brake tracks), cosmetics, improper assembly or abuse. **This guarantee is valid for the original owner of Polaris wheels. Labor and return shipping costs are not covered by Ascent. Ascent and its distributors reserve the right to refuse warranty or crash replacement guarantee to any person who, at our sole discretion, abuses our products, programs, or warranty policy. Damage caused by misuse, abuse, or intentional damage will not be covered by either policy.
OMNIBALANCE DESIGN PHILOSOPHY
The Omnibalance Design Philosophy guides our wheel design. It is no longer sufficient to produce wheels that are fast - they need to be stable and controllable, they need to inspire confidence so that you dare to push yourself to the absolute best.
We have identified five key factors for a wheel's performance, and have designed Polaris to excel in all of them:
- Steering Stability
- Aerodynamics
- Comfort
- Traction
- Response
