Coating Free

Coating Free

This is BTLOS' most advanced manufacturing process. Due to high-quality carbon fiber and specially formulated epoxy (resin) along with state-of-the-art molding and manufacturing techniques, BTLOS rims come out of the mold without blemishes or defects in their finish eliminating the need for painting and/or clear coating and also saving weight.
USED FOR: Premium Series
Smooth Inside Wall

Smooth Inside Wall

The traditional inflatable bladders used by many manufacturers to maintain the rim's shape during the molding process lack the ability to closely control the final shape of the rim. As a result, although most carbon rims appear smooth and seamless on the outside, they are marked by irregularities and weaknesses on the inner surface of the rim. Each irregularity is a potential point of failure.
Using a molding process we call ''SLW'', BTLOS employs proprietary high-pressure bladders and specific solid silicone forms to tightly control rim shape, producing virtually void-free rims with perfectly smooth walls (inside and out) resulting in finished rims that are truer, lighter, stronger, more durable rims and wheels.
USED FOR: Premium Series
Spoke Hole Angles

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.
USED FOR: Premium Series / Standard Series
Graphene Special Braking Surface

Graphene Special Braking Surface

By incorporating graphene into our design we are able to increase braking power by 50% in all conditions while limiting heat build-up to less than 150 degrees. These improvements lead to a more durable, stronger brake track along with improved braking performance in wet conditions and during long descents. Our new brake track can also include a patterned surface specific to customer requirements or specifications. (OEM service available). Learn More
USED FOR: Premium Series / Standard Series
Super High TG Braking Surface

Super High TG Braking Surface

Extremely high heat resistance at the brake, testing TG values up to 250 degrees at 100pis test conditions. Ordinary rim TG can only reach 180 degrees.
USED FOR: Premium Series / Standard Series
One-Piece Molding

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.
USED FOR: Premium Series / Standard Series
High TG Epoxy Resins

High TG Epoxy Resins

BTLOS uses the highest TG epoxy resin to increase rim resistance to high temperatures created under braking. Our exclusive nano-resin formula combined with Toray's new ULTRA series products guarantee that the rims are resistent to heat build up and that they retain 100% of their rigidity regardless of the conditions while also saving weight vs. traditional TG resins.
USED FOR: Premium Series / Standard Series
Twine Tec

Twine Tec

Twine technology can solve the problem of using a material with insufficient ductility to produce a full three-dimensional surface product that is prone to local tearing or wrinkling of the material. This will ensure even balance of weight and strength around the circumference of the rim.

Two Carbon Fiber Types

Two Carbon Fiber Types

Rims made from different types of carbon fibers may thus be characterized by greater stiffness and strength. Therefore, in order to provide you with the best possible rims, we use two different types of carbon fiber (Toray T700, Toray T800) in the production of BTLOS rims. BTLOS premium rims are a combination of T700 and T800 carbon fibers.

Secure Lock

Secure Lock

The newly patented Secure Lock nipple of Sapim is a locking mechanism that prevents nipples from untightening. As a result, the nipples do not loosen during riding, and thus the wheel remains perfectly centered and rigid for a longer time.
