Size Tuned Kinematic is a four-pivot suspension technology developed exclusively by CUBE. It guarantees that every frame in every size will have exactly the same dynamic properties for the designed and factual travel and response. To reach this, separate links had to be developed for each frame size.

The basis for our carbon frames is High Performance Composite, a combination of various high performance fibres. The fibre consists of multiple filaments, and its tissue is impregnated with a resin matrix to form the carbon tissue from which we build our HPC models The strong fibres are fixed in position and are protected against chemical influence and mechanical damage. The choice, mix and direction of the fibres are determined by the forces expected to act on specific areas of the frame. Our HPC models excel in high absolute stiffness (Nm/°) at low weight and a very good stiffness-to-weight ratio STW (N/°/kg).

In this process possibly dangerous folding is eliminated by constant control of carbon fibres during the curing process. By using fixed internal forms at junction points the quantity of resin is considerably reduced and the fibres bonded more tightly together. The result is increased product safety and improved STW values.

The requirement for a continuously active and fully usable travel: The rear triangle is not affected by pedalling or especially braking forces. Regardless of the fact that a variety of other possibilities exists, we employ a four pivot chain stay construction. Here, one of the pivots is located between the dropout and the chain stay; this ensures that braking does not have a negative effect on the movement of the rear wheel. Thereby via the appropriate positioning of the remaining pivots, we obtain the finest riding qualities for our fullsuspension bikes in terms of uphill as well as downhill abilities.

On polished and brushed aluminium and all HPC frames the logos and graphics are applied in multi-layer wet paint. We use this surface treatment technology mainly to save weight.

To protect our high-end aluminium frames, they are built with the CUBE Frame Save System replaceable derailleur hanger. The thread is in the hanger and not in the frame as usual. In case of a crash, this hanger can be easily and quickly replaced by a new one.

Joining our AMS/Size Tuned Kinematic rear train with the shock, we have developed our CUBE-specific 3D Active rocker. Next to its special three dimensional design this cold forged rocker has a very high specific density which gives it an extreme torsional stiffness.

Elaborative developed kinematics are only able to function correctly if the associated suspension shocks is properly tuned to it. Connected with the new Fox Float RP23 Boost Valve shock and the DHX RC4 shock, we could achieve the best optimised performance.
