TECHNOLOGY:

 

SLN (Self Locking Nipples): Thanks to the patented self-locking nipples, the perforated nylon sphere is inserted into the edge of the spoke nipples. his totally eliminates the spokes problem when decreasing speed, allowing the wheel to stay centred and tensioned over time.

 

BBS (Ball Bearing System): A 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 reduced lack eliminates power dispersion exerted on the wheel.
