SR:ONE - Ultra Light/Climbing

Achieving the perfect balance of lightness and strength requires mastery of materials, design, and testing. Each carbon ply is precisely oriented, resin systems are carefully tuned, and every tube profile is validated through rigorous analysis and iteration. Performance standards are continuously refined to push beyond convention. The result: a frameset that weighs just 639g—proof that strength and minimal weight can coexist.
