Ursus Athon disc 'superlight' clincher A cycling wheel optimized for disc braking system. Athon are the perfect synthesis of the must have features that you’ll need from a road racing cycling wheel. Yet selected for training by professional teams which have chosen Ursus, it has stood for reliability in classic races such as the “Strade Bianche”. An aluminum low profile (24 mm) rim, associated with a pair of smooth Ursus CNC machined hubs, makes Athon extremely comfortable, supersoft on roughness, slight uphill and responsive at the same time.
TECHNOLOGIES URSUS creates its wheels always looking to create the best quality on structures and finnishings:
SLN SELF LOCKING NIPPLES 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.
BBS BALL BEARING SYSTEM 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.
DWS DEEP WELDED SYSTEM This System allows a perfect resistance to traction, torsion, and tear at the vulnerable point of the wheels rim. The wheels rim is designed in close connection with alloy 50886 H34 and then glued to the hill through the injection of high structural features, according to the process EPX Scotch WEID.
