CORIMA’s expertise and innovation in carbon composite materials are recognized globally. We’ve been manufacturing high performance carbon wheels for more than 30 years. Because of in-house production we control all the steps in the manufacturing process; from the design to the final assembly and packaging. Our wheels are individually moulded by hand using prepreg carbon fibers, entirely hand-made in our workshop in LORIOL sur DRÔME, FRANCE.

In 2010 CORIMA created the first MCC wheels (full carbon- hub, spokes & rim), with a unique design and innovative technical specifications ! That same year, the MCC wheels won “The Star of the Design’s Observeur ” in Paris and the “JEC Awards ”. In 2012, the MCC won the Gold Medal at the London Olympic Games thanks to the victory of Alexander VINOKUROV

The objective behind the design of MCC wheels is to utilize groundbreaking technology to deliver enhanced performance.

Three years of research and development with a single clear focus: designing and producing the PERFECT disc brake wheelset to cover all aspects of racing, from lightweight and superior stiffness for climbing to optimizing aerodynamics and control for fast descends and flat roads.

• Torsion Box
• Ultra light DX system
• Carbon aero spokes
• Full carbon rim Tubular or TLR
• D2T Double torque technology

Carbon aero spokes
The new shape of the MCC DX wheels has been designed toreduce air drag. This new design results in a 9% (front wheel) *and 18% (rear wheel) * aerodynamic improvement. MCC wheels are assembled using only 12 spokes (FR and RR). This pairing of the spokes leads to a considerable reduction in resistance and influence from cross winds. Giving the rider more control. The placement of the 6 anchor points of the spokes inside the rim, uniformly distributes the extra weight of these anchors. This setting creates a very low level of rotational inertia, perfect for high-speed climbing and for rapid accelerations during races.

D2T Double torque technology
Corima’s D2T system on the rear wheel overcomes the biggest obstacle for FULL carbon disc brake hubs -torque in both directions from pedaling and braking. We succeeded in producing a full carbon disc brake rear hub that is strong enough to withstand these forces. Front wheels only need to be strong enough to deal with this torque when braking. Rear wheels need to be able to handle these forces during acceleration AND braking. Our unique Y-shaped carbon configuration where 2 spokes are joined ensures the distribution of forces during acceleration AND braking. The Y-shaped joint allows us to produce a FULL carbon wheel that is unrivalled in performance, weight, strength and stiffness with a unique and race-ready appearance.

Torsion box technology
CORIMA’s secret behind its incredible stiffness : weight ratio is hidden in the rim structure. All CORIMA wheels are filled with a structural foam and a horizontal UD carbon fiber bar to increase overall rigidity and strength. The Torsion Box concept created and patented by CORIMA in the 90’s, significantly reduces the flex found in ALL hollow carbon rims. This stiffness allows for enhanced power transfer in the most direct way possible to the ground, to push the bike forward. Because of this internal structure, the wheel is able to keep its trueness better under load. This core also helps to absorb both vibrations and sound for a quiet and more comfortable ride. Each CORIMA wheel is done by hand which makes them unique.
