TORAY Carbon Fiber Composite Materials.In the field of carbon fiber composite materials, they are the world's leading manufacturer of PAN-based carbon fibers.These materials in various forms are used in aerospace and many other applications.
BTLOS applies firsthand knowledge and research, along with industry-leading materials and technologies to create rims and wheels that are optimized to deliver extremely light weights without sacrificing the strength and durability demanded by the world's best riders.
A lay-up process where by carbon layers are stacked/overlapped at 45-degree angles creating very high ateral stiffness and improved impact resistance while maintaining responsiveness and efficiency under power.
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.
Spoke Hole Angles
BTLOS can drill spoke hole angles to match or compliment the spoke angles created by the hub flange (as provided by the customer). 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.
All BTLOS 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.
