We optimized our new dropout design based on the Syntace X12 through-axle system, enlarging the area of the frame where the hanger is mounted. We can now fit the longer Direct Mount hangers. Shifting precision and stiffness is therefore improved. With the new design it's also possible to swap the whole contact area of the axle with the hanger should the system be worn out.
The new STEREO , FRITZZ and HANZZ models are built using Advanced Hydroforming. Conventional hydroforming processes cannot achieve these custom shapes and technical advantages. As this manufacturing method reduces the number of welds, the weight is reduced while durability is increased. All
We ran innumerable tests to develop the Agile Ride Geometry in our series of big wheel bikes. We also added the 27.5in wheel size 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 26in 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 the same as on our 26in bikes. These measures lead to a natural riding position. Every mountain biker will feel immediately at home on a CUBE 29er or 27.5.
Our Efficient Trail Control series works so that everyone can have more fun on the trail. With 27.5 and 29er wheel options our frames cover the widest range of riding on every terrain you can imagine. The low leverage ratio and linear rate curve makes the bike very sensitive, avoids bobbing and offers full usable travel all the time. Steep seat tube angles and slack head tube angles make these dream machines ready for action on the descent where you can use the full amount of travel to be on the safe side.
The key requirement is for continuously active and fully usable travel, with the rear triangle unaffected by pedalling or especially braking forces. There are a number of ways of achieving this CUBE favours a four bar design with a chainstay pivot. Here, one of the pivots is located between the dropout and the chainstay, ensuring that braking does not have a negative effect on the movement of the rear wheel. By carefully positioning the remaining pivots, we obtain the finest riding qualities for our full suspension bikes both uphill and downhill. This fact is proven by many top test results in leading magazines over the last few years.
Dropper seat posts are getting more and more widespread, but to integrate them optimally in the frame, they have to be factory fitted. With the Stealth Ready frames, it is possible to build in a dropper seat post with internally routed cables, which besides the clean look, helps prevent any cables getting jammed. The exit of the cable on the frame if not required will be sealed with a cover for protection.
This steerer tube design is stiffer than a conventional straight steerer and yields a more secure ride feel even in difficult terrain. Minimal flex at the front of the frame means the greatest possible steering precision. 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 Trail Motion Rocker features optimized leverage ratios for every bike and intended use, giving fast reacting yet stable suspension in every situation. The computer-designed one piece rocker construction gives maximum stiffness for the best suspension performance while still being extremely lightweight.
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.
The engine is the critical part of an Ebike because of its weight and its junction to the regular drivetrain. These factors present a real challenge for the frame design. This is why CUBE developed an innovative new frame construction for the new Ebike generation: simultaneously being the cradle for the electric motor, the pivot for the rear link and the seat of the shock eyelet, the very complex area of the bottom bracket is made of two forged halves. The groove in the front section together with the specially formed down tube is home for the power pack which in this way has a very low position in the frame triangle. The positive outcome is an extremely low center of gravity supporting an agile riding characteristic while achieving a super rigid bottom bracket area.
For our high end bikes we use High Performance 7005 Aluminium alloy which has a very low density combined with high strength due to the alloy elements and the hardening heat treatment. By triple butting or even quadruple butting (as in the REACTION , HANZZ and AERIUM models) to give different wall thicknesses in one tube, aluminium tubes are reinforced where required and made lighter where possible. In this way, we succeed in getting material where its needed most. In addition we use special tube shapes, manufactured with hydroforming technology to better cope with directional forces. The low density and high strength as well as the butting and the hydroforming technology enable us to make high performance frames with an ultimate level of stiffness.
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.
