FAQ

All-road, le meilleur des deux mondes

Pour associer la performance et la légèreté d’une roue de route avec le confort et la versatilité d’une roue de gravel, nous avons développé une jante en carbone au design unique.

Ses 40 mm de hauteur et sa légèreté (1600 gr la paire) lui assurent un comportement irréprochable sur l’asphalte, tandis que sa largeur interne de 23 mm sans crochet appelée « hookless », est conçue pour recevoir des pneus tubeless ready d'une section comprise entre 28 et 50 mm, vous permettant d’adapter vos choix de pneumatiques et de pression en fonction de vos envies et des terrains rencontrés. Ne craignez plus les bitumes dégradés, les pistes de gravier ou les pavés détrempés, l’Essentia 40 vous laisse fixer vos propres limites !

A hookless rim

The Essentia 40 is designed for use with tubeless tires for improved comfort, grip and puncture resistance. At CORIMA we have chosen the hookless technology for the rim. The straight inner profile saves weight and is more versatile, while the lack of hooked sides also means the wheels are sturdier and offer better handling by allowing the tire to perfectly follow the shape of the rim.

As a result, the Essentia 40 is formidable on asphalt combined with 28mm tires and can accommodate gravel tires up to 50mm to take on the most demanding surfaces.

Performance meets strength

To ensure even power distribution, optimal performance and improved sturdiness, the Essentia 40 is equipped with our new Ratchet system with 36 teeth and a 10 degree angle of engagement.

This mechanism inside the hub has been specifically designed to handle higher levels of torque in order to guarantee exceptional reliability when faced with intensive use on rough roads.

The CORIMA touch

Efficient, versatile and accessible, the Essentia 40 all-road wheels are 100% Made in France in CORIMA’s own workshops. 24 stainless steel spokes, arranged in an exclusive CORIMA-specific pattern, take care of stiffness and reliability, while the hub is custom-designed to withstand intense gravel use.

The rim construction draws on the very best of our expertise: structural foam inside the rim, selection and master layup of the best 3k carbon fibers, an elegant and distinctive look all come together at a value unique on the market today.

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.
