All GTC models are built using this complex manufacturing process. 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.

We ran innumerable tests to develop the Agile Ride Geometry in our 2012 series of big wheel bikes. This year we add the 650B wheelsize to the very well received portfolio. Three 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. Last but not least we kept the BB height same as on our 26" bikes. These measures lead to a natural riding position. Every mountain biker will feel immediately at home on a CUBE 29er.

Internally routed cables offer many advantages. Cables are protected from dirt for longer life, weight is saved thanks to the absence of external housing and the bike has a clean, sleek appearance.

This new steerer tube design is stiffer than a conventional straight steerer and generates a more secure ride feel even in difficult terrain. Minimal flex at the front of the frame means that the greatest possible steering precision is generated. With the larger steerer the forks become more rigid. At the same time weight is saved due to the absence of bearing shells as the lower bearing is fully integrated into the head tube. On all of our CUBE carbon models the upper bearing shells are also directly in the frame, so that once more a few grams are saved and the energy transfer is very direct.

The postmount system is found at all carbon fiber frames, the high end models of the touring bikes and the upper range aluminum models. The bolts and the IS adpater aren’t needed anymore, less parts mean less weight. In this case we save 30 grams. This may not sound a lot. But as you see, there is potential to save weigth in every detail.

With press-fit bearings, the bottom bracket bearings are pressed directly into the frame and not screwed in as usual. This gives a wider bottom bracket shell and allows to build a wider down tube and more broadly-spaced chainstays. Every millimetre of additional width gives a significant improvement in lateral stiffness.

On polished, 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 from damage, they are built with the CUBE Frame Save System replaceable derailleur hanger. The mounting 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.
