    Technology

    ONE-PIECE MOLDING

    Since the rims do not have the weaknesses associated with the various components of any of the different designs, they are continuously molded using techniques known as "one-piece molding". Because of this, the rims are perfectly symmetrical and evenly rolled.

    COATING FREE

    Due to high-quality carbon fiber and specially formulated epoxy (resin) along with state-of-the-art molding and manufacturing techniques.Just clear coating or none coating.See the finish info.

    SPOKE HOLE ANGLES

    We drill spoke hole angles to match or compliment the spoke angles created by the hub flange. Matching the spoke hole drilling angle in the rim to the spoke angle of the hub/hub flange allows the nipple to be better aligned with the spoke when the wheel is tensioned resulting in fewer broken spokes and nipples.

    FLATNESS AND ROUNDNESS

    Our molding and manufacturing techniques which allow us to control rim flatness to within 0.15mm and roundness to withing 0.2mm making it incredibly easy to build perfectly true, strong wheels.

    HAND-BUILT

    All wheels are 100% hand built to exacting standards by well trained wheel builders using only the best available components. All of our wheels are rigorously tested to guarantee accurate spoke tension and precise truing.
