Straight out of the box, the Undefeated is a race-ready beast of a machine built upon the original Undefeated’s winning pedigree. Designed for mastering fixed-gear crits, The Undefeated is our lightest production frame ever, featuring Y9 double-butted aluminum alloy tubing, an oversized tapered head tube, and an Essor USA full carbon fork that come together to create a stiff, responsive, and fast ride.
The Undefeated complete build features premier, competition-grade components. The Essor USA Aerodash Crankset is built with 7075 aluminum and uses an external bottom bracket to ensure maximum power transfer, while the seamless construction promotes smooth airflow over the crank for greater aerodynamics. The Essor USA Bolt v2 Wheel Set features a large cutout flange design on the hubs to improve stress distribution while also reducing weight; making the wheelset light enough for competition and durable enough to take a beating on the streets. Compact Drop Bars round out the complete build by providing comfort and quick transitions between hand placements.
Our most responsive and powerful machine yet boasts nothing but premier parts and components, making the Undefeated II the favorite track in track and fixed-gear racing.
