They say you should never change a winning formula - but why not? Our completely reworked Stereo 140 C:62 29er has all the benefits of its test-winning forerunner, but improves on it in every way. With the best currently available full carbon chassis, optimised geometry and innovative components, the Stereo C:62 140 is another milestone in the history of CUBE full suspension trail bikes. It's a machine on which you can really let rip...
We kept two of the previous versions' best qualities on this bike: an ultra-light, stiff and extremely robust state-of-the-art full carbon chassis built with our advanced Twin Mould Monocoque technique, and the exceptional Efficient Trail Control (ETC) suspension dynamics with 140mm travel. Beyond that, we re-visited everything to make this extraordinary 29er even better. We improved our Agile Ride Geometry by adding a longer top tube and even more standover clearance. Dropouts both front and rear use the wide Boost hub standard for better steering precision and improved wheel durability - particularly important when you're searching for the right line on tough singletrack. This is a frame that leaves our competition - and yours - in the dust.
Our full carbon Stereo deserves only the best. Race Face's Turbine Cinch crank is a great match for several reasons. First, it features a super stiff 30mm oversized aluminium axle and detailed CNC finishing. And second, its 34x24T chainrings mesh perfectly with Shimano's new XT 2x11 transmission to provide ideal big-wheeler gear ratios. We also fitted Shimano's new XT brakes, offering unmatched reliability. To complement the super-efficient rigidity of the chassis, we took the edge off trail hits with the new Fox 34 and its FIT4 dampers and wide 110mm Boost axle, paired with a Float DPS shock at the rear. They work together to tame the trail and keep the rider in control, at all times. Light and stiff DT CSW AM 3.8 tubeless-ready wheels with Boost axles acclerate quickly and roll easily. And, naturally, the SL comes with a RockShox Reverb Stealth seatpost for even more trail riding fun.

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.
This technique uses a complete core to provide the perfect frame form during the lay-up process. As with the Twin Mould technology, precise inserts are used to ensure extra strength at high-stress frame points. This combination offers maximum control over fibre orientations during the lay-up and production process. The Advanced Twin Mould high-tech carbon manufacturing process translates to outstanding product safety and quality together with optimum weight and stiffness characteristics.
The Agile Trail Geometry carries over the Agile Ride Geometrys benefits but with more focus on aggressive trail use. This can be achieved through a more compact frame construction with an even lower top tube and improved standover height. The result is more freedom of movement on the bike for the rider and a lower centre of gravity which guarantees agile handling and more riding fun.
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.
Sophisticated suspension kinematics are only able to work correctly if the associated shock is properly tuned. We researched and found a specific shock setup in cooperation with Fox Racing Shox, using extensive testing for almost every CUBE full-suspension model.
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.
Trough the full Di2 Integration the Dura Ace Di2 battery is completely fitted within the frame. The Shimano junction box is placed aerodynamically in the stem which makes charging and servicing a lot easier as it can be done via the junction in the stem. Another distinct feature is that it can be easily dismounted and mounted for transporting the bike.
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.
The post mount rear brake system is found on all carbon fiber frames and top aluminum full suspension models. Two bolts and the IS adpater arent needed anymore, and fewer parts means less weight. In this case we save 30 grams. This may not sound a lot. But there's potential to save weight 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 us to build a wider down tube and more broadly-spaced chainstays. Every millimetre of additional width gives a significant improvement in lateral stiffness.
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.
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 position of the wheel is done by an insert in the right-hand dropout which is secured by a bolt. The main advantages of the Syntace system are quick and simple changing of the wheel, reliable position of the brake disc and higher stiffness of the rear of the bike. This allows the assembly to be made lighter than a conventional through-axle.
Boost 148mm technology provides precise handling, on every trail, in every situation. The hub flange moves 3mm towards the outside on both sides. It increases the stiffness of a 27.5? wheel by 14% and, for a 29er wheel, by 21%. The reason is the spokes wider support in comparison to the 142mm hubs used previously.
