For high end, we use High Performance 7005 aluminium alloy which has a very low density combined with high strength due to the special alloy and the hardening heat treatment. By triple butting or even quadruple butted tubing, aluminium tubes are reinforced where required and reduced where possible. In addition we use Special tube shapes, manufactured with Hydroform technology to better cope with the directional forces. The low density and high strength as well as the butting and the Hydroform technology enable us to make high performance frames with an ultimate level of stiffness.

Here particular attention has been given to the fact that irrespective of body size EVERY rider can have the optimum and identical riding experience. Here on a model-by-model basis we have differently designed the linkage geometry so that all frame heights have the same travel and suspension ratio (STK).In addition the kinematics have been optimised specifically to travel in respect of sensitivity, drive and no bossing. For this it was necessary to specially position all rear pivot points. Whether the rider is large or small, with any of these models he will always have the optimum ride experience.

In this system, a cone is used to form a play-free connection. It is only necessary to tighten the axle from one side. The main advantages of the Syntace system are: quick and simple changing of the wheel, a stabilised position of the brake disc, a higher stiffness of the rear drive train and a lighter weight compared to a conventional thru axle. The advantages of the Syntace through-axle system are: easier fitting and removal of the rear axle, stable brake disc position (thus less sliding) and improved rear assembly rigidity values. Hence the X12 weighs less than conventional through-axle systems

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.

A plain tube is placed in a mould with the specific form. The tube is filled with a mixture of liquids, often an oil mixture, which is put under high pressure. It presses the material into the negative form of the mould and gives it its shape. The manufacturing of this part concentrates, in the first place, on technical and stability issues related to the forces and stresses the part will be subject to as well as on reduced weight. Besides, hydroforming also has some great design aspects. Hydroforming enables us to make optimally light and strong shapes and internal partitions for our frames.

With press-fit bearings, the outer bearing ring is pressed directly into the frame housing and not screwed-in as usual. With its wider housing, the down tube and the chain stays are joined with the full width. Because the width of the housing is a parameter in calculating the stiffness, every millimetre of additional width gives a significant improvement of lateral stiffness, whilst retaining the comfort-bringing resilience of the chain stays.

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.

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.

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.

The Postmount breaking absorption makes it possible for us to save extra parts. The not needed IS adapter with bolts saves approx. 30 g. This may not seem much, but it shows the potential comprised in the details.

Internally routed cables offer many advantages: clean appearance, cables are protected from dirt and therefore have a considerably longer life and the not required external housing saves weight.

The colour of our aluminium frames with Eloxal finish is reached by anodising (a chemical process). After this treatment, the aluminium is 1000 times more scratch-resistant than before.

We are not the first ones to present 29ers to the market. But it's only for 2012 that suspension fork manufacturers have been able to fulfil our demands concerning the geometry. We ran innumerable tests to develop the Agile Ride Geometry in our 2012 series of big wheel bikes. Two important details lead to the very agile character. Increased fork offsets let us achieve the same trail as our 26” bikes without having to steepen the head angle, thus maintaining generous toe clearance to the front wheel. Secondly we shortened the chain stays without compromising the seat angle. We invented a patented construction to mount the front derailleur to give us more tyre clearance while keeping a conventional seat angle, leading to a perfect riding position for every rider size. These measures lead to a natural riding position. Every mountain biker will feel immediately at home on a CUBE 29er.
