Retired Undefeated · 2024
Undefeated Track - Graphite : Prism
Built for fixed-gear crits, the Undefeated Track in Graphite / Prism was the race-ready track machine of State Bicycle Co.'s Undefeated series, introduced in 2023 and retired in May 2024. State called its Y9 double-butted aluminum frame the lightest production frame it had made, and paired it with an oversized tapered head tube and a full carbon Essor USA fork. The build leaned on Essor USA parts too: an Aerodash 7075 aluminum crankset with an external bottom bracket and Bolt v2 wheels. It ran a 48x16 gear ratio with compact drop bars, and a 55 cm frame weighed 16 lb 6 oz.
