When you are pushing your absolute limits, you need to trust your gear.
This is why we designed POLARIS - 69mm wheels that will carry you through any condition.

 

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 rim that works admirably fast. During testing, the rim was faster at 10m/s and 13.3m/s than our 50mm Zenith wheels, and had an improved stall angle. This means more speed, over a wider range of wind conditions, than a mid-depth carbon wheel.

 

CALMING STABILITY

Blowing away the common wisdom that deep-section wheels are hard to handle, the Polaris 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.

 

EXCEPTIONAL TRACTION

Starting with a 28mm tire, we decided to maximize tire volume by choosing an immense 23mm internal width to allow these tires to plump up for increased air volume and lateral stability. While 23mm internal is wider than some rims entirely , our wide, tubeless-ready rim bed allows tires to withstand cornering forces confidently, while the added volume of air absorbs shock from rough roads and delivers exceptional traction.

 

LIVELY RESPONSE

A responsive wheel feels alive—ready to respond to the rider’s inputs. Liberal use of ultrahigh grade carbon fibers, exceeding the typical T700 and T800 grades used in most rims, and careful fiber placement allow for each Polaris rim to weigh just 530-550 grams for the Ultralight version, and 560-580g for the Standard version, one of the lightest in its weight class. By minimizing the weight, the rotational inertia of the wheels is reduced, producing a lively feel that shatters expectations of what a deep-section wheel should feel like.

The highest-end Polaris wheels with DT Swiss 180 hubs will sport a raw rim finish  - a striking reminder that its owner has chosen the best of the best.

 

BUILT TO WIN

Every Polaris wheel is hand-built with pride in Singapore. We believe that in the age of machine-produced wheels, a hand-built, hand-tensioned wheel still provides the best quality, durability, and trueness. We are partnering with BuiltWheels, one of the best wheelbuilders in Singapore, to give Polaris the best possible construction.
