KEY TECHNOLOGY
Freehub fit with 3 pawls and 9 teeth ratchet
The patented pawl design with 3 pawls and 9 teeth allows each tooth to fit closely and make close occlusal contact with the 48 teeth surface in the ratchet ring when turning. The design of pawl with 3 pawls and 9 teeth steps is more effort-saving when pedaling.
Wing spoke
The WING SPOKE was designed to outperform the current crop of high-end spokes that are found on today’s finest racing wheels. The WING is more than just another lightweight, bladed spoke. Inspired by the nose cone of an airplane, it offers the highest level of aerodynamic performance of any spoke on the market today. Wheel builders will also appreciate the ease of working with the WING. Its one-piece, butted design reduces potential weak spots, while its rigidity helps prevent twisting or breakage when tensioning.
360° carbon fiber rim reinforced ring
360 degree full carbon fiber reinforcement ring can reduce the bump caused by the wheel spoke building.
UD light carbon fiber
UD Carbon-fiber Rim.
Precision bearings
Precision bearings provide riders with a smoother road cruise.
Hand-built wheels
Using precise measuring equipment and specialized tool, our technicians adjust and correct lateral and radial deviation and center the rim.
Special drilling angle
To drill the holes with proper angles in precise calculation for mini wheels can optimize the spokes to be built in straight lines.
