Polyimide Tubeless Rim Tape for CARBON rims

Install it right the first time. No hidden mistakes.With most conventional printed or opaque tapes, the installation imperfections are hidden or difficult to notice. You install blind. With absoluteBLACK, you can see exactly what you’re doing, inspect the entire rim bed, and correct any bubbles or creases before mounting the tire. It’s a more controlled, repeatable installation process.

Our tubeless rim tape is built from engineering-grade polyimide, not generic packaging film. At just 100µm thickness, it is thin enough for perfect conformity, yet strong enough to handle the demands of modern carbon road systems. Unlike standard polyimide tapes found in the electronics market—typically paired with weak silicone adhesives—our tape uses a different, higher-tack adhesive system optimized specifically for carbon rims. We also utilize a thicker adhesive layer, increasing overall compliance so the tape can better adapt to a wide range of rim shapes and internal profiles. This enhanced conformity allows the adhesive to follow subtle surface variations, filling micro-irregularities and improving real contact area across the rim bed. The result is a more uniform bond, reduced risk of trapped air and poor contact, and a consistently reliable tubeless seal. Yet still removes cleanly without residue.

A subtle level of elasticity further allows the tape to follow rim contours effortlessly. During installation, small air bubbles or creases can inevitably form—but thanks to the transparent construction, they are clearly visible and can be easily pushed out to the sides with your fingers. This helps ensure full adhesive contact and a dependable airtight seal from the start
