Description

Our new 45MCC tubeless wheels in TC (tubeless hook) version feature an internal width of 22 mm and an external width of 28 mm, allowing for tires ranging from 25 to 34 mm. Optimized for 28 to 30 mm tires, they ensure unmatched performance and stability. Now 90g lighter, they offer ultimate versatility without compromising on efficiency. Their 100% carbon construction provides an exceptional stiffness-to-weight ratio and gives them a unique look. Specific and patented design. These wheels are entirely handcrafted, using only premium carbon fibers, with each carbon fiber carefully positioned to optimize power transfer.

Disc brake wheels, with carbon spokes molded onto a CORIMA star-shaped hub (hub with ratchets).
The 45MCC wheels feature a sleek and aesthetic design, with the rim finish in matte varnish revealing the 3K carbon fibers, and the matte black decals are placed under the varnish.

User's manual

Mandatory conditions of use for road tubeless wheels

Tires compatibility

  • 22TC (tubeless crochet) wheels can be fitted with 25 to 34 mm tires (ISO 5775).
  • In tubeless setup, the use of Tubeless Ready tires is mandatory.
  • With inner tube, any type of tire is allowed (TubeType or Tubeless Ready tire).
  • The maximum inflation pressure is 7.5 bar (109 psi) for a 25 mm tire or 6.7 bar (97 psi) for a 28 mm.

Tips and restrictions

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

  • 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 from Velox)
  • When inflating, 12g CO2 cartridges limited to 6bar are allowed.
  • CO2 cartridges higher than 12g, high flow pumps and compressors are prohibited.
  • Use only plastic tire levers.
FAQ

Exceptional stiffness-to-weight ratio for peak performance

To truly elevate wheel performance, one must seek more than just lightness. While the metric of weight is easily quantifiable, an equally critical factor often overlooked is stiffness. Stiffness defines a wheel's ability to translate power and wattage into pure speed.

Introducing the MCC EVO, a masterpiece boasting the most superior weight-to-stiffness ratio in the market, exceeding its rivals by an impressive 15% in average stiffness. Even in its pursuit of featherweight design, the MCC wheel emerges as a formidable competitor against the most robust monobloc spoke wheels. The enigma behind this excellence lies in the distinctive MCC design and the exclusive utilization of top-tier carbon fibers.

These high quality carbon fibers are meticulously draped by Corima around structural aerospace foam, amplifying the stiffness of the rims and unleashing the full potential of power transmission

Answer any challenge.

To adapt to the heterogeneous asphalt of mountain roads and variable weather conditions, the 45MCC is available in Tubeless Crochet (TC) version. The benefits are numerous:

  • Optimized comfort with the ability to adjust pressures without losing performance.
  • Improved dynamic qualities and handling.
  • Superior puncture resistance and versatility, with the option to install tires of various sizes.
  • With inner tube, any type of tire is allowed.

Performance meets strength

To ensure even power distribution, optimal performance and improved sturdiness, this wheel 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.

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.

Attack. No matter where, no matter when.

Setting the pace on the steepest ascents and never-ending climbs comes down to your legs... But not only. Discover the impressive acceleration capabilities of the MCC:

  • D2T technology, which absorbs pedaling and braking torques in a single piece of carbon and ensures exceptional precision and blistering acceleration.
  • A patented CORIMA spoke system, featuring 12 paired carbon spokes for unrivalled stiffness and durability.
  • New MCC Ratchet hubs, with smooth, durable construction and a 17% increase in the transfer and distribution of pedaling torque. Perfect for lightning-fast acceleration.

Carbon spokes

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.

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.
