Ursus designed the Alcor wheels with precise specifications: rims in alloy Al 6069 WTB, 28 holes, 23mm inner channel, Sapim D-Light straight pull spokes, XD40 Ursus hubs. The mix of these components guarantees comfort, ease of use and thanks to the particular design of the rim profile it meets the needs of the most technical bikers.
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.
