  • Ursus Miura C37 carbon clincher

    Road racing cycling wheel Miura C37 is the Ursus concept for clincher. A 37 mm profile UD monocoque rims with HPS shield that provides improved dissipation of heating derived from prolonged braking on the carbon. Equipped with aluminum hubs featuring low friction technology Ursus BBS, carbon-aluminum hubs are available as well on request.

    URSUS creates its wheels always looking to create the best quality on structures and finnishings:

    Thanks to the patented self-locking nipples sphere perforated nylon is inserted into the brim of the spoke nipples, This totally eliminates the problem, when decreasing speed, of rays, allowing the wheel to stay centered and tensioned over time.

    System where four hub bearings are inserted for optimum fluidity. In the area behind the rear wheel hub there are two bearings in a line that restrict the pin from bending. The reduction of the lack eliminates the dispersion of power exerted on the wheel.

    An important system of inorganic reinforced fiber. Where the heat which is created from the rim during the breaking process is blocked by this particular shield, allowing the internal structure not to affect the integrity of the carbon..

    The carbon used in these rims and soaked by a particular resin is very resistant to high temperatures created from the brake pads on the rim. This part causes a lower deterioration of the carbon in time and thus a better performance of the final rim.

    This carbon fiber is designed to work in the line of force of the main load. This allows to maintain a very high rigidness/ weight ratio. The rim with this type of fiber is lighter and more resistant to loads and is reinforced with the addition of material in the nipples.
