The patented design begins with a revolutionary clamping which spreads the forces asymmetrically about 260 ° (instead of the usual symmetrical 180 °) on the cap and handlebar mount. The steerer clamp uses three screws and a curved slot for tensioning to reduce stress on the steerer.
The basic body is forged from 7050'er aluminum 3D, is milled in the inside in order to reduce the weight. Black anodised premium quality Cro-Mo steel bolts are used for the screw connection. The screws have a smaller diameter (M4) than usual, which still saves some weight without affecting the strength or stiffness.
