Designed for mastering fixed gear crits, The Undefeated II is our lightest production frame ever, featuring 7005 Double-Butted Aluminum 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 II 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 wheel set 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.
