Usury Contyrol System. Rims with have a dug-out track in the braking sides for the visual detection wear of the rim.
Diamond Turned Side. Rims with have grounded braking sides to ensure a perfect and modular braking. It allows extreme precision on the parallelism of the braking surfaces of the rim.
Nipple Mass Compensation. A continuous differential milling process of the internal contour of the rim. With this system the additional mass of the spoke nipples is compensated for by deeper milling at their contact points to the wheel. In this way the wheel is more balanced and the mass evenly distributed.
