Proving that you should never judge a book by its cover, the Stereo 120 SL 29's understated looks disguise its prodigious trail-taming abilities. By combining a brand new, lightweight and trail-orientated frame with fast-rolling 29er wheels and top drawer components, we've created an extraordinary comfortable, agile and capable off-road machine that'll handle anything you care to throw at it. It is, in many ways, a wolf in sheep's clothing. From the slick, sleek and reliable Shimano XT brakes and transmission to the Fox 34 Factory fork and DPS EVOL shock - both with Kashima coatings for the ultimate in bump sensitivity - we've selected only the best parts to pair with our design team's latest masterpiece. A CUBE dropper post for those tricky, technical descents and light, strong Newmen wheels to keep you rolling complete the setup. Whether you like to ride multi-day adventures or just enjoy singletrack blasts on your home turf, the Stereo 120 SL 29 has got your back.

Which is more important - looks or performance? If you were to ask the CUBE engineering team, they'd probably tell you that each is as important as the other. The Stereo 120 SL 29's elegant appearance is certainly no accident. It combines hydroformed, triple butted aluminium tubes with advanced Efficent Trail Control kinematics and completely revised Agile Trail Geometry to stunning effect. From the way the seatstays flow seamlessly via the rocker linkage - complete with hidden pivots - into the top tube, to the torture-testing we undertake in our own lab to measure ultimate strength and stiffness, every millimetre of this frame has been finessed to extract the very best performance and looks. Internally routed cables even include stealth dropper post routing. But we don't want you just to admire the looks - we want you to ride it. Because we're confident that you won't want to stop...
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 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.
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 spoke’s wider support in comparison to the 142mm hubs used previously.
The Agile Trail Geometry carries over the Agile Ride Geometry’s 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.
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.
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.
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 post mount rear brake system is found on all carbon fiber frames and top aluminum full suspension models. Two bolts and the IS adpater aren’t 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.
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.
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.
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.
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.
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.
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.
