NINJA - FRAME PLATFORM
The new NINJA model represents the model series designed for freeride and bikepark riding. The foundation is a very low = playful frame with a rear triangle travel of 180 mm and a shock absorber that is 222 mm long with a travel of 70 mm. The rear wheel suspension uses AGang proprietary four-pivot technology, the DLP (Drive Link Pivot). The frame is built with plain gauge (solid wall) tubes made of Al 6061, using TIG welding followed with thermal treatment. The high-grade industrial bearings and the SSH (Stainless Steel Hardwear) technology ensure smooth operation of the rear wheel travel. The latest sandwich design of the short linkage lends important lateral rigidity. An indispensable frame structural element is the mounting system, which is compliant with ISCG’05 (International Standard Chain Guide), allowing easy mounting of the chain guide on the frame. At the same time, the standard maximizes the guide functionality.

NINJA - SUSPENSION SYSTEM OF FRAME PLATFORM
The NINJA model series uses a system based on the four-pivot rear wheel suspension principle. The main difference is the position of the pivot in the rear triangle above the rear wheel axle. This design makes it possible to shift the main pivot, next to the bottom bracket, between the large and middle chainring. The result is an optimized position of the “virtual pivot”, which influences the performance of the entire four-pivot mechanism. A DLP with an optimum position and shape of the top linkage contributes to the overall springing characteristics depending on the purpose of each model series (socalled leverage ratio / rear wheel suspension characteristics).
The NINJA series uses a top linkage with forward travel and an almost horizontal shock absorber position. This design achieves high shock absorbing performance even for minor vibrations as well as progressive hardening of the shock absorber towards the end (the last 20%) of the rear wheel travel.
Besides being sensitive even while braking, the DLP suspension of the rear triangle is characterised by minimal pedal kickback (when the cranks kick back during the shock absorber compression) and chain length extension or reduction.
