Description

Designed for aggressive downcountry riding, high-speed singletrack, and technical XC courses, the 2026 Polygon Syncline DR9 Frameset* merges featherlight carbon performance with expanded trail capability. Constructed from Polygon's premium ACX carbon fiber, this frame features progressive trail-inspired geometry with a slacker head tube angle, longer reach, and short chainstays for razor-sharp handling on technical descents and efficient power delivery on steep climbs. Equipped with a 12x148mm Boost rear end, SRAM Universal Derailleur Hanger (UDH) standard for direct-mount drivetrain compatibility, full internal cable routing, and internal dropper post compatibility, it delivers a stiff, compliant, and future-proof foundation for a top-tier custom build.
