Stereo 140 HPA 27.5 Frame black anodized
At its best when being pushed hard, the Stereo HPA 27.5 frame is versatile enough to tackle any trail challenge that you throw its way.
Only when the best technologies in alloy manufacturing are combined may the resulting frame carry the name High Performance Aluminum (HPA). Its optimum strength to weight ratio comes from features like the elaborately hydroformed triple butted tube set, tapered head tube, PressFit bottom bracket and AHX drop outs for an X12 thru axle. Internal cable routing further adds to the clean and dynamic look. The Stereo HPA 27.5’s wonderfully playful handling comes from our refined Agile Ride Geometry and the Efficient Trail Control kinematics, which deliver perfect suspension performance on any trail. The new frame design with a steeply sloping top tube enhances stand over clearance and the new forged rocker arm creates a distinctive look.

Technologies High Performance Aluminum
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 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.
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 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.
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 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.
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.
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.
