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.
LCS LANE CONTROL SYSTEM The sides of the wheel rim are CNC machine anodized with high precision unit. This process allows efficient braking due to increased friction and a high degree of parallelism between the pad and rim.
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.
