ONE – SRAM Red (Disc)

Aero
ONE – SRAM Red (Disc) is a carbon aero road bike (2024), by Factor. This bike is aimed at riders who want a sporty road feel without a full race fit, leaning toward a sporty riding position, with a surface profile that is best matched to paved roads. The main strengths in the metrics are a clearly aero-focused setup for faster road riding, good fit flexibility for dialing in rider position, and strong speed potential on smoother terrain. Compared with more specialized alternatives, the compromise is a firmer ride feel than comfort-first options and more of a flat-to-rolling terrain bias than a climbing focus.
