The Stereo 140 C:62’s stiff, superlight monocoque full carbon frame including carbon rocker linkage – all made using the latest Advanced Twin Mould technique – represents the pinnacle of current carbon frame construction technology. Everything from the oversized cross-sections to the PressFit bottom bracket, tapered head tube and aluminium chainstay hardware is optimised for the lowest possible weight, maximum stiffness and greatest strength. Customised Agile Trail Geometry (ATG) and Efficient Trail Control (ETC) with the four-pivot suspension design creates a fast chassis that won’t be knocked off its stride – livelier than its big 29er brother, but with plenty left in reserve to push those boundaries.

C:62 Carbon Technology
The unusually high carbon content is achieved during production by using three perfectly integrated techniques. Advanced Twin Mold: We minimise imprecise overlaps by accurately fitting individual carbon layers’ overlap regions during the monocoque building process. The result is a frame with no superfluous weight – every gramme counts. We also use a solid core in the centre of the frame during the manufacturing process, which is removed when the frame is finished. This reduces the buildup of folded material and increases the safety and integrity of our lightest frames.
Special carbon fibre material choice: An extraordinary combination of materials is needed to make the best quality carbon. By using High Modulus fibres, we’ve made the C:62 frame extremely stiff. Finely dispersed nanoparticles are integrated in the resin that bonds the two carbon layers. Thanks to these tiny particles, the durabillity of the frame is improved – and it’s also less sensitive to impacts and better able to withstand external forces. This combination of nanoresin particles and High Modulus fibres is what makes a C:62 out of a SHPC frame.
Adaptable X12 Hanger
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.
Agile Trail Geometry
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.
Integrated Cable Routing
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.
Integrated Post Mount
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.
Press Fit BB
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.
X12 Through Axle
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.
Wet Paint Surface
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.
Advanced Twin Mold
The Advanced Twin Mold process eliminates any dangerous folding by continuous control of carbon fibers during the curing process. This is made possible by an internal form which provides the perfect frame form during the layup process. Each individual fibre remains precisely in position as it cures. In this way less material can be used as the individual layers can be more accurately and reliably positioned. This production method also makes it possible to increase the carbon fibre proportion in line with anticipated loadings at specific points on the frame. All SUPER HPC models from 2014 on are manufactured using this high-tech method.
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.
