Basso
Race
Astra Sram Rival 2×12 ETAP AXS is a carbon race road bike (2023), by Basso, from the Astra lineup. Rider-wise, it fits riders who want a sporty road feel without a full race fit, leaning toward a sporty riding position, while being best matched to paved roads. Its profile is strongest in areas like good fit flexibility for dialing in rider position, a balanced aero profile for mixed road priorities, and strong speed potential on smoother terrain. What it gives up slightly is a firmer ride feel than comfort-first options and a value score that depends more on priorities than pure price efficiency.
