Undefeated Track - Pearl / Tie-Dye

Race-ready out of the box was the pitch for the Undefeated Track, and this Pearl / Tie-Dye version from the Undefeated series was introduced in 2022 and retired on July 3, 2023. Designed for fixed gear crits, it was built on Y9 double-butted aluminum tubing with an oversized tapered head tube and an Essor USA full carbon fork. Essor also supplied the 7075 aluminum Aerodash crank, run on an external bottom bracket for power transfer, and the Bolt v2 wheels. Gearing was 48x16 on 25c tires, with recommended clearance of 25c up front and 28c out back. A 55cm weighed 16 lb 6 oz.
