The NRS design is the result of a collaboration between Giant and Renault Sport, better know for their successes on the Formula 1 circuit. One of Renault’s suspension engineers, Pascal Tribotte, happened to be an MTB enthusiast. He talked over his ideas during a chance meeting with a salesman in a Giant dealer’s shop. The management of both companies saw the opportunities, and the NRS design was born.
Giant have introduced the world’s first no-power-loss rear suspension: the NRS design, which stands for No Resonance System.

Previous attempts at rear suspension had often been modelled on the motorcycle, ignoring — and as a result exaggerating — the disruptive effect of the cyclist’s enormous, very slow moving pistons (or legs). To compensate, the suspension had to be ‘locked out’ to prevent bobbing and bump absorption, or left ‘soft’ to absorb both bumps and energy. The NRS design is very different, though it may not look it. It uses the rider’s pedalling input to its advantage. It’s a bit like a see-saw — on one side the wheel is pushing up to compress the spring, on the other the rider is pushing down trying to extend the spring. The result: equilibrium.

The system is set up with no ‘sag’, which is to say that the shock is not pre-compressed by the rider’s weight. Bumps compress the rear shock, while pedalling input tries to extends the shock— but there’s no movement available, because there’s no sag. So the shock can’t extend any further when the rider pedals out of the saddle: it climbs like a hard-tail, and descends like any other dual suspension bike. “I’m definitely faster against the clock,” notes Giant XC racer Rune Hoydahl, lending support to Giant’s claim that, on average, the NRS adds 2-4 km/h to maximum XC speeds.

The NRS design is fitted to all of Giant’s cross-country dual suspension bikes. Top of the range is the XtC Team, based on sub-2kg 6013 aluminium frame.
