Aero
Rapha AMANI Edition – Ostro Gravel – SRAM Force w/ Power Meter is a carbon aero road bike (2024), by Factor, from the Rapha Amani lineup. Rider-wise, it fits a wide range of riders thanks to its fit flexibility, with a setup that gives you a balanced riding position, with a surface profile that is best matched to paved roads. Its profile is strongest in areas like a clearly aero-focused setup for faster road riding, good fit flexibility for dialing in rider position, and balanced, versatile speed for everyday riding. At the same time, 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.
