Cube Sting 140 HPA Pro 29 Frame grey'n'greenSting 140 HPA Pro frame is a first-class trail performer.Even big bumps are just sucked up by our Sting 140 Pro. There are a dozen new lines on the descent which you never noticed before. With the Sting 140 we have built a universal 29er full suspension bike for riders who want to start all-mountain experiences and love the fun enabled by 140mm of travel. A totally new triple butted 7005 aluminum frame is the base, using Advanced Mechanical Forming for optimized tubing. With 120mm of travel the FSP 4-link works as a high-performance suspension chassis. ETC lets the bike behave easily on every terrain because braking and pedalling don`t compromise the performance. The balanced ARG – Agile Ride Geometry – lets you feel confident even on longer rides through its playful but reliable handling.

TechnologiesHigh 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.
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.
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.
Agile Ride Geometry
We ran innumerable tests to develop the Agile Ride Geometry in our series of big wheel bikes. We also added the 27.5in wheel size to the very well received portfolio. Three important details lead to the very agile character. Increased fork offsets let us achieve the same trail as our 26in bikes without having to steepen the head angle, thus maintaining generous toe clearance to the front wheel. Secondly we shortened the chain stays without compromising the seat angle. We invented a patented construction to mount the front derailleur to give us more tyre clearance while keeping a conventional seat angle, leading to a perfect riding position for every rider size. Last but not least we kept the BB height the same as on our 26in bikes. These measures lead to a natural riding position. Every mountain biker will feel immediately at home on a CUBE 29er or 27.5.
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.
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.
