Making a tried, tested and proven product even better is one thing. But creating something entirely new while still retaining its predecessor's qualities - that requires genuine innovative genius. For the "New" Stereo we didn't just tweak every detail; we redeveloped it from the ground up. The result is a brand new trail e-MTB which will tackle anything in its stride, including the most technical of trails. Available in a total of 7 frame sizes from 16 to 23 inches and with 27.5in or 29er wheels - so everyone will be able to find the perfect bike for their needs.
Our widely-admired Agile Trail Geometry (ATG) and Efficient Trail Control (ETC) suspension design form the basis for the four pivot 7005 HPA frame. The Tuned Drive Position (TDP) allowed us to reduce chainstay length by an impressive 20mm, making for noticeably more agile and lively handling out on the trail. Because that means you're likely to be riding faster than ever, we've also fitted 148mm Boost hubs on all our 2nd generation Stereo Hybrids, giving greater wheel rigidity and better reliability. Gear cables are also run internally now - hidden away, tidied up and protected.
A long list of impressive components is definitively topped by the most powerful drive currently available - the Bosch CX. With up to 75Nm of torque and 600W of peak power, this is a monster hill climber. Backing up all this power is the new high performance 500Wh battery, which opens up epic rides without the need to constantly cast a worrying glance at the battery display. Shimano's new-for-2016 11 speed XT transmission not only guarantees flawlessly reliable gear shifts, but the 11-42 cassette also offers an extremely large gear ratio range. Combined with its silky smooth shifter and legendary reliability, it's a setup that makes 2x groupsets all but redundant - and the matching hydraulic disc brakes are every bit as good in terms of stopping power. RockShox's smooth Yari suspension fork, with technology based on the legendary Pike, adds stiffness to the package with 35mm stanchions. And Answer's Atac AM wheels shod with wide 2.35in Schwalbe Nobby Nic tyres transfer drive and braking forces to the trail with impeccable reliablity.

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.
