SRAM Force 1 AXS Power Meter

Find a Dealer

While our new X-Range gearing technology has brought much of the simplicity of 1x drivetrain to a 2x setup, there are still disciplines where a single-ring drivetrain shines. The SRAM Force 1 AXS power meter offers improved aerodynamics for triathlon and time trial bikes, thanks to a direct mount aero chainring option with integrated power. It also provides the simplicity that cyclocross racers crave. And the tighter gearing range is perfect for road racing and riding in flatter terrain, where a wide range would go unused.
