700c Road U50 Rim Non-Disc

Tairin offers road track-brake carbon (traditional non-disc) rims in two options. With a U shape cross sectional profile, and in heights of 38mm and 50mm.

 

Our Tairin road track-brake rims are symmetrical clinchers, tubeless compatible and engineered with our proprietary design: focusing around the sidewall, brake surface, wall junctions, nipple bed, and composite material layup. One of the key performance points we set to archive, is braking performance during initial and long braking periods, for brake fade prevention. 

 

We also explored all carbon layup possibilities to increase overall stiffness while minimizing Rc (Resin content) ratio to a 70/30 mix, by laying 3k fabric in between layers of the rim to increase performance. We utilize filament winding methods in the nipple bed area for continuous fiber winding.

 

All in all, we refined our rims towards high strength as our top priority. We pass a rigours test, of loading single spoke holes with 300kgf spoke tension.

 

Braking surface is designed flush to the rim U-shape sidewall and it contours around to be ergonomic with the articulation of rim brakes. Brake surfaces are not basalt coated, but embedded into a special 1k single strand bond of basalt fibers. Our braking tests show initial temperature raise, but following a decrease over the length of braking. Impact tests follow during high temperature tests, to emulate worst case scenarios and we are confident that our engineering provides product longevity against carbon delamination.

 

Both options of rim dimensions are based with an external width of 24.8mm and internal width of 18mm. These rims are perfect for 23mm and 25mm tires.
