Ursus alloy wheel ORION DISC (Set) for Clincher – RD40 142X12 – Black – SHIMANO

Dedicated to gravel aficionados and bikers who enjoy group outings on racing bikes

Orion disc is an aluminium rim for disc brakes with absolutely hybrid performances: a product within the reach of any cyclist. These wheels run fast and smoothly on asphalt, but they also perform well on unpaved roads and mixed routes, the favourites of gravel enthusiasts. Off-road enthusiasts will also appreciate the compatibility with Campagnolo’s Ekar group.

Its generous internal width is designed to give the bike stability, while the ultra-resistant 25 mm rim is perfect to absorb the small bumps and vibrations typical of a surface that is not perfectly smooth. This means that the bike is easier to control, for example on bumpy asphalt or on gravel. The riding comfort is superior, also thanks to the option to install a wide range of tires (tubeless-ready or clinchers between 26 and 46 mm). The right rigidity, necessary for intense bursts of energy, is ensured by the asymmetrical shape designed to optimize the rim tension by balancing the forces that come from the brakes and sprocket cassette.

These features also make Orion ideal as a technical choice for intensive training and endurance outings with friends. No doubt on reliability: even on this model you will have all the Italian quality of the new Ursus RD30 hubs for disc brakes, tested and certified by our pro-team cyclists after hundreds of hours of training sessions.
