All-road, the best of both worlds

To combine the performance and lightness of a road wheel with the comfort and versatility of a gravel wheel, we have developed a carbon rim with a unique design.

Its 40 mm height and its lightness (1600 g per pair) ensure impeccable behavior on asphalt, while its internal width of 23 mm without a hook, called "hookless", is designed to accommodate tubeless ready tires of a section between 28 and 50 mm, allowing you to adapt your choice of tires and pressure according to your desires and the terrain encountered. No longer fear degraded asphalt, gravel tracks or wet cobblestones, the Essentia 40 lets you set your own limits!

A hookless rim for more comfort

The Essentia 40 is developed for mounting with Tubeless tires which guarantee increased comfort, grip and better resistance to punctures. At CORIMA we have chosen hookless technology: thanks to a straight internal profile, the rim is lighter and more versatile.

Without hooks, they are also more resistant and improve handling by allowing the tire to perfectly match the shape of the rim. Thus, the Essentia 40 is formidable on asphalt with sections of 28mm and also accepts gravel tires up to 50mm to tackle the most demanding surfaces.

Robustness and performance

To ensure uniform power distribution, optimal performance and increase its robustness, the Essentia 40 is equipped with our new Ratchet system based on 36 engagement points with an engagement angle of 10 degrees.

We have introduced a mechanism inside our hub which is based on a toothed crown system. The latter has been designed to manage higher torque levels and thus guarantee exceptional reliability in the face of intensive use conditions on degraded surfaces.

The Made in CORIMA signature

High-performance, versatile and accessible, the Essentia 40 all road wheels are manufactured in France in our factory in Loriol-sur-Drôme. Rigidity and reliability are ensured by 24 stainless steel spokes arranged in a unique way, according to a specific CORIMA pattern, as well as by hubs specially developed to withstand gravel use.

The construction of the rim integrates the best of our know-how: structural foam inside the rim, mastery and selection of the best 3k carbon fibers, while offering a clean and unique look as well as value for money. unique on the market.
