Carbon wheelchair wheel DECiSiV Race28" tubeless hooked

Recognized among the best in the market, our Corima wheels are the choice of discerning athletes seeking unmatched performance. Trust Corima for a race where every push counts. From track racing to CFD and CRR testing, our know‑how shapes every engineering decision.

A winning wheel for every race
Designed to meet the demands of the most committed athletes, this wheel is made for marathon's races as well as shorter races. It delivers instant power transfer, outstanding stability, and exceptional efficiency, no matter the intensity or duration of the effort. This wheel embodies years of research, real‑world data, and uncompromising performance standards.

Reduced weight while preserving the same stiffness
Lighter, stiffer and faster to ensure instant power transfer and sharper responsiveness under load.

Optimized rim for modern tyres
We engineered the DECiSiV RACE with a rim width perfectly matched to today’s wider, high‑performance tyres. This optimized interface reduces rolling resistance and boosts efficiency over long distances.

Delivered without handrim.

FAQ

Stiffness, lenticular shape, and aerodynamics

Lenticular construction for maximum stability and optimized aerodynamic efficiency. On this disc wheel, the inner and outer profiles feature different designs to better accommodate camber constraints. This approach aims to achieve optimal aerodynamic efficiency (combining with wheelchair) while maximizing structural stiffness.
Increased stiffness ensures every push is converted into forward motion with no energy loss.

Tech & Fast wheelset

This wheel has been engineered down to the finest detail:

  • 20 mm internal width (20 TC)
  • Specifically optimized to pair perfectly with 23 to 30 mm tires, delivering the ideal balance between efficiency, grip, and comfort.
  • You can select the tyre size that best suits the specific requirements of your race.

With our in‑house CRR (Coefficient of Rolling Resistance) testing protocols, we evaluated multiple configurations to determine the optimal shape.

High grade structural foam

Since the beginning, CORIMA’s disc wheels have integrated structural foam and the DECiSiV RACE is no exception.

Placed within the sidewalls of the rim and sandwiched between two carbon skins, the high‑grade PMI (polymethacrylimide) structural foam ensures an exceptional stiffness‑to‑weight ratio.

This architecture keeps the wheel perfectly stable at high speed while delivering instantaneous power transfer.

How we made it

Built on Corima’s proven track record of expertise

Since 1991, Corima has been redefining standards with its monobloc wheels for racing wheelchairs. Built to withstand extreme conditions, these wheels offer the stiffness and strength needed to handle the camber and forces placed by athletes on the push-rims. Recognized among the best in the market, our Corima wheels are the choice of discerning athletes seeking unmatched performance. Trust Corima for a race where every push counts.

Understanding para-athletics

With this wheel, Corima reaffirms a unique expertise in high-performance carbon engineering and a commitment to para-athletes: delivering uncompromising products designed to win.

Contrary to what many people think, it is in wheelchair racing that wheels are put under the greatest stress. Indeed, opposing camber position causes the wheels to be constantly subjected to bending forces on their inner face, on the wheelchair side, combined with the repeated full‑force punches delivered to the pushrims to drive the wheels powerfully.
From a mechanical standpoint, CORIMA carbon wheels quickly proved to be the best on the global market, and we are extremely proud of this recognition from athletes whose achievements speak for themselves.

Validated by the greatest champions

Our partnerships with French and international professional athletes and synergies with continental and national teams enable us to test and optimise our products. Beyond our partnerships, many athletes choose to compete with our products. This is a testament to their quality and reliability in meeting the demands of high-level competition.
