Technology:

MoMag
MoMag stands for Mounting Magnet and refers to a type of fastening for spokes in the rim bed. The spoke nipples are inserted into the rim through the valve opening and guided to their destination with a magnet. The spokes are screwed into the nipples as standard. This also allows for easy maintenance and replacement of spokes.

Undrilled Rim Bed
The rim bed is continuous and has no holes for nipples. The nipples are inserted over the valve opening and guided with a magnet to the connection point of the rim. This eliminates the need for rim tape, increases the durability of the rim and allows for higher spoke tension, resulting in greater stiffness.

DRSC
Directionated Rim-Spoke Coupling is an exclusive rim-spoke connection system. This way, the rim, spokes, nipples and hub are matched to each other, achieving the same tension value at every point. All critical areas of increased voltage are eliminated.

USB
USB stands for Ultra Smooth Bearings. These are ceramic bearings for hubs that significantly increase the smoothness of the wheels, minimize weight and make maintenance manageable. USB bearings are about 50% smoother than standard bearings. This means that more power is converted into direct propulsion and is no longer lost through friction.

Two-to-One Spoke Ratio
To avoid energy loss, two-to-one wheels are equipped with double the number of spokes in critical areas. For rear wheels, this accounts for the increased forces on the drive side. Front wheels have twice as many spokes on the side of the brake rotor.
