Advanced Ride Technology

Advanced Ride Technology, or A.R.T., is the direct link between engineering and experience. More than a single suspension platform, A.R.T. is a system that w...

Norco’s engineering team strategically manipulates pivot locations to precision-tune suspension kinematics, ensuring that every full suspension bike will excel in the environment it was designed for. For downhill applications, we increase rearward axle path for a more controlled ride over gnarly, unpredictable terrain. For cross-country we increase pedaling efficiency and small bump compliance for a faster, smoother ride.
