Retired Undefeated Road · 2026

Undefeated Disc Road - Graphite / Prism

The Undefeated Disc Road in Graphite / Prism brought the Undefeated geometry and style to the open road, now with disc brakes. Part of State Bicycle Co.'s Undefeated Road series, it was introduced in 2023 and retired in September 2026. A double-butted Y9 aluminum frame with an oversized tapered head tube and a full carbon Essor USA fork and steerer made for a stiff, responsive ride. The drivetrain was a simplified 1x11, a 46t ring on a State Bicycle Co. All Road 1 crank with an 11-28t cassette. Tektro flat-mount mechanical discs, tubeless-capable wheels, and 28c tires finished it, across six frame sizes for riders from 4'10" to 6'6".
