GIANT NRSGiant's first NRS non-energy loss shock absorber system is the world's first no energy loss shock absorber system.
What is NRS?
Facing bumpy roads and various obstacles on the road, what is most needed is a shock absorber system with superior performance that will not affect the forward speed.
The handling and comfort of the bike should be improved and should not interfere with other aspects of the bike's performance. Here, "comfort" does not mean turning your bike into a comfortable lounge chair for lazing. We mean that you can safely drive at 30 miles per hour.
Riding over gravel (ahem, you get what you pay for) without having to slow down to 20 miles an hour.
A perfect shock absorber can properly handle the two forces faced when riding, one is the rebound force caused by rough terrain, and the other is the rider's own pedaling force.
In short, it can not only absorb the rebound force caused by the terrain, but also avoid the energy loss caused by compressing the shock absorber when pedaling. Satisfying these two points is an excellent shock absorber system.
There are two secrets to Giant's original NRS: precise frame four-link geometric design, extended shock absorbers and no preload setting (No Sag).
The linkage mechanism of the rear frame (linkage arms) is similar to the principle of a seesaw. On one side, the wheel is pushed upwards, compressing the spring; on the other side, the rider steps down to extend the spring.
When the shock absorber is set to No-Sag, it is fully extended, and the NRS provides the same pedaling feel as a rigid frame.
NO RESONANCE SYSTEM (NRS) NO RESONANCE SYSTEM (NRS) GIANT's NO RESONANCE SYSTEM (NRS) does what no other system can do!
It avoids unnecessary vibrations and responds sensitively when bumps occur; professional cycling magazines even declared the NRS system to be the best-designed off-road bicycle in history. Even though the NRS has been around for more than five years, it is still unrivaled on the market.

NRS can reduce unnecessary vibrations by distinguishing the source of force from pedaling and bumps; the force from ground impact will compress the suspension system like other shock absorbers, but the force of pedaling will keep NRS stretched; when pedaling,
The NRS will act like a hardware frame, and when encountering any bump force, the 3.75" travel shock absorber will immediately compress and absorb the bump force. The secret of the NRS design lies in the main rotating shaft and the lower link shaft (rear chainstay shaft)
); when pedaling, due to torque movement, the chain will pull the rear wheel axle downward, and this downward movement will drag the upper suspension strut (seat stay) and rear arc rocker arm, making the front arc shape
The rocker arm pulls up to extend the shock absorber, so all your pedaling force is transmitted to the rear wheel, achieving no energy loss. NRS is different from other suspension systems in that it does not have to rely on the rider.
When you sit on the car, the preload (SAG) of the shock absorbers is compressed (most suspension systems will have preload to function during some small bumps, but the cost is energy loss), while with NRS, the shock absorbers remain at
Fully extended and ready to absorb shock with a full 3.75 inches of shock absorber travel (with SAG's shock system, the actual usable shock travel will be lower than the original because the shock absorber has been used by the rider
Compressed due to weight) 1. The shock absorber can be set to no preload when it is in the "top out" position 2. The position of the swing arm shaft causes the force from the pedal to produce a downward pulling force on the axle 3. Arc rocker
The arm continues to extend the shock absorber, reducing vibration during acceleration 4. The suspension system responds to any small bumps on the ground. Another benefit of the NRS no-sag setting is that the suspension system will not be affected by the rider's movements.
The car's handling characteristics will not change due to braking; for example, when you ride a rear suspension model that relies on sag, the front triangle of the car will rotate slightly because the main shaft is pressed downward. This is due to the sag.
The change lowers the spindle and reduces the angle on the frame; when braking, the rider's weight will shift to the front of the car, thus subtracting the weight of the rear, causing the suspension to return to its unloaded state.
The frame geometry will cause unpredictable handling problems when cornering or braking in a straight line; a correctly set NRS can avoid this situation. Although GIANT has always believed in the power of the rider's pedaling.
, but we also believe that rider impressions do not represent the whole truth, which is why we have developed an information collection system to help us obtain more accurate data to support the performance of NRS. Many riders think weight.
It is the only measurable performance data. For example, the lighter the weight, the faster you can ride. However, experiments also show that even if a car with a suspension system is heavier than one without a suspension system, it can help the rider use it.
Less energy, more efficient work; the suspension system also helps the rider to pass bumpy roads at a faster speed.
