Traditional tubeless setups carry a hidden compromise: heavy, intricate Presta cores constantly vulnerable to latex sealant seizure and restricted airflow. absoluteBLACK engineered past this century-old limitation. By migrating the mechanical interface down into the rim cavity, a completely unobstructed path unlocks uncompromised airflow, facilitating instant tire seating without the garage-compressor headache.
Crafted from long carbon fiber-polymer composite injection rather than basic CNC aluminum, these structural marvels slice rotating mass at the outermost edge of the wheel where reduction translates directly into acceleration. Powering up steep alpine switchbacks or punching through loose gravel, the wheels respond with an immediate, unburdened tactile snap.
Every inflation becomes a seamless, non-serviceable luxury. The tire's internal air pressure acts as the primary sealing kinetic energy, continually pressing the internal plunger closed with absolute reliability, even through high-speed descents and severe technical impacts.
FEATURES
Bottom-Sealing Architecture
Eliminates traditional removable Presta valve cores to establish a completely direct, restriction-free airflow path that remains immune to sealant accumulation.
Long Carbon Fiber Composite
Provides tensile and yield strength exceeding 6061-T6 aluminum at roughly half the material density to significantly minimize outer rotational mass.
Half-Moon Support Elements
Preserves unhindered air and sealant channels within the rim bed even when compressed by dense gravel or mountain bike tire inserts.
Plunger-Lock Mechanism
Leverages internal tire pressure to continuously drive the seating interface closed, eliminating accidental opening at high rotational velocities.
Direct Injection Pathway
Facilitates seamless liquid sealant replenishment directly through the valve body via syringes or standard applicator tubes without core extraction.
