Norco's performance road frames feature Applied Road Compliance (ARC) technology, which optimizes the vertical compliance to lateral rigidity ratio for race and endurance applications. ARC seat stays are designed with a distinctive bow shape that works like micro-suspension to dampen fatiguing road vibrations. ARC technology enables us to maximize rider comfort without any sacrifice to the lateral stiffness that gives a high performance road bike its pedaling efficiency and explosiveness.
ARC Endurance:
Seat stays are slender and feature a very pronounced bow shape that makes them extremely effective at dampening road vibrations. Chain stays are broad and stiff to ensure optimal pedaling efficiency, and they are engineered to be slightly longer to deliver a more stable ride experience.
ARC Race:
Seat stays are slender and feature a less pronounced bow shape that still delivers effective road vibration dampening. Chain stays are broad and extremely stiff to deliver maximum pedaling efficiency, and they are engineered to be slightly shorter to deliver a highly responsive ride experience.
