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.

 

DSS (Deep Spina System): The two parts of the wheel's rim are joined by using calibrated stainless steel pins. This process of interference creates an elevated resistance to traction.
