The Stereo Hybrid HPA 140 SL 27.5 is the undisputed top dog of All-Mountain e-bikes. Given the innovative energy that we've ploughed into designing this bike, it's fair to call it one of the most advanced Hybrid full suspension bikes of all time. The features exclusive to the SL version will make you the envy of everyone. And once you've experienced the performance and subtly unfolding power of the new Bosch CX drive, you'll want to race it along your favourite trails - and seek out and explore new singletrack - time and time again.
The 7005 High Performance Aluminium (HPA) frame is based around our much-admired Agile Trail Geometry (ATG) and Efficeint Trail Control (ETC) suspension design. Using Tuned Drive Postion meant that we were able to trim the chainstays by an impressive 20mm, making for noticeably more lively handling on the trail. And, since that means you'll probably be riding faster than ever, we specced wider 148mm Boost hubs on all 2nd generation Stereo Hybrids to improve stiffness and reliablity. Gear cables run internally - hidden away, tidied up and protected from damage. Another highlight is the CUBE Performance Cover, designed especially for All-Mountain use. Integrated impact protection absorbs the initial energy on making contact with the ground, while the shock absorber takes on and neutralises the rest. The drive unit and frame are optimally protected against impacts - and the included chain guide keeps the chain away from the chainstay on even the roughest trails.
We selected components to perform one function: provide 100% All-Mountain performance. Incredibly responsive suspension performance and massive reserves for tackling the roughest terrain come courtesy of a brace of Fox's brand new suspension components: a Float 34 fork up front and Float DPS shock at the rear, both with slippery Kashima coating. Even in appalling weather, Shimano's new XT brake will stop you reliably and quickly. SRAM's XO1 11 speed drivetrain, working in combination with Bosch's most powerful CX Drive Unit, makes double chainsets redundant thanks to its astonishing 420% gear ratio range. This latest Bosch drive boasts 75Nm torque and 600W of peak power, making it a formidable weapon with which to tackle even the steepest of mountain climbs. Grippy Schwalbe Hans Dampf tyres - in Super Gravity trim at the rear - with a RockShox Reverb Stealth dropper post, Race Face Carbon Cockpit and 760mm wide bars all make light work of technical singletrack.

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.
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.
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
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.
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.
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.
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.
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.
This elaborate procedure with doubled weld seams has two advantages: On the one hand, it improves the firmness of the
weld seams and minimizes the load peaks on the tube welds through energy flow and on the other hand, it helps the frame
to a better and more organic look due to the smooth and hardly noticeable welds.
