Giant NRS
NO RESONANCE SYSTEM (NRS)

Giant’s No Resonance System (NRS) does what no other system can; cancel out bobbing while still being sensitive to bumps. NRS has been heralded by the cycling press as the best cross country racing design ever built. Now over five years old, it still has no equal.

The NRS system eliminates bobbing by separating pedaling forces from bump forces. Impact forces from the ground compress the shock much like other suspension systems. However, since pedaling forces (torque) cause the shock to extend, NRS performs like a rigid frame when pedaling. Yet, even small bump forces will compress the shock (3.75" travel) and absorb impact.
