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 the 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 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.
This 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.

DownloadState Bicycle Co. provides a five-year warranty against defects in manufacturing for all bicycle frames and forks, valid only for the original purchaser and non-transferable. This warranty does not cover damages stemming from misuse or lack of maintenance. Essor USA brand carbon fiber forks are excluded from this coverage, but they do come with a separate two-year warranty.
For all non-consumable parts/accessories, State Bicycle Co. offers a one-year warranty against manufacturing defects. These parts include pedals, crankset, wheels, hubs, spokes, stems, carbon fiber forks, seat posts, and handlebars. However, regular wear and tear on items such as tires, bar tape, saddles, chains, tubes, grips, paint, and brake pads are not covered under any warranty.
The warranty period is 5 years from the date of activation, covering only the initial purchase. Any replacement items needed within the warranty period will be covered until the end of the original warranty term, not an additional 5 or 1 year.
For electronic bikes, there's an 18-month warranty for motor, electronics, and battery. For other parts, refer to the information stated above.
To activate your bicycle warranty, we must receive proof of professional assembly. This ensures you have the safest and most optimized riding experience with your new bike.
