Tips and restrictions

Running tubeless tires requires specific care when it comes to installation and maintenance.

  • Use only plastic tire levers
  • When installing the tire, 2 layers of 0.1mm thick rim tape must be installed against the inner rim bed to ensure an airtight seal. (FTUB27-10 de Velox)
  • CO2 cartridges, high flow pumps and compressors MUST Not be used to inflate TSS tubless tires on the Essentia wheels.
FAQ

Tubeless tires, to keep on rolling.

The WS EVO wheels are available in a tubeless version with hookless technology. This allows for a large choice of tire widths, the option to use lower inflation pressures as well as higher resistance to punctures. The wheels’ dynamic performance is also enhanced by their lighter weight and the optimized transition between rim and tire. When riding in the mountains, the sometimes rougher roads or unpredictable weather call for a versatility and resilience that only tubeless tires can offer, only adding to the wide-ranging skills of the WS EVO.

Carbon performance

If one thing sets CORIMA apart, it is the mastery of carbon fiber technologies. The WS EVO's 3K carbon rim, reinforced with structural foam, is a lightweight yet rigid gem. Handling and performance at this price point are unrivalled: the hyper-responsive WS EVO set the tone as soon as the road rises. They are precise and reliable on descents, with exceptional handling and control thanks to their minimal wind resistance and optimized stiffness.

Technologies combined.

The R2 spokes and aerospace foam within the carbon rim give the WS EVO their unique feel and performance. Their extreme efficiency is further enhanced by the S EVO Ratchet hubs, which add to the exceptional responsiveness, especially on the steepest gradients. By increasing the pedaling torque transmission and distribution by 17%, the new ratchet system optimizes power transfer within the rear hub whilst reducing friction to a minimum.

The CORIMA expertise.

Built in our workshops at Loriol-sur-Drôme, in France, the WS EVO wheels are the fruit of CORIMA's longstanding expertise and experience. We apply the same uncompromising quality and finish to all our models, striving to offer a unique experience that seamlessly blends performance, precision and a distinctive style, endorsed by athletes the world over.

How we made it

Global approach

Since we entered the bicycle industry in 1988, CORIMA has always been at the forefront of carbon wheel design technology. With our own patents and unique design philosophy, we are constantly innovating and improving our wheels to stay one step ahead of the competition and give you even more performance.
Our philosophy has always been to design the best performing wheels with a global approach. This includes lightness and reliability, of course, but also essential performance factors such as stiffness, aerodynamics and rotational inertia.

Designed and produced in Loriol-sur-Drôme

When our engineers imagine a new product, they simultaneously think about the industrialization process of this one. Indeed, thanks to our history and our industrial origins, we design all the manufacturing means that will be used in the realization of your wheels (special machines, molds, tools) as well as the test benches necessary for the improvement and the validation. This global control of the design and the means of production assures our customers of the required performances and an exceptional quality-price ratio.

Validated by the greatest champions

Our partnership with Astana for more than 11 seasons, allows us to test and optimize our products with the best athletes in the world. In addition to the partnership with Astana, many athletes, and not only those we have in sponsorship, choose to evolve with our products. This is a sign of their quality and reliability to meet the expectations at the highest level.
