REACTION HYBRID HPA

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.

Aluminium Superlite

Extremely high tensile strength heat-treated 7005 aluminium alloy is developed for the highest requirements. It is very stiff, fatigue resistant, corrosion resistant and has high elongation. Our Superlite tubes are double butted, giving very light tubesets with a high level of stiffness.

Onepiece Design

Welded joints in our high-quality aluminum frames are specially finished via this method and create the impresssion of seamless tube design. This generates the visual effect of moulding and ensures high load bearing capacity.

Tapered Steerer

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.

Easy Mount Kickstand

The Easy Mount Kick Stand is a new system developed and designed by CUBE. The base of the stand is mounted from below to a fitting plate integrated to the frame and fixed with a through bolt. This kick stand is extremely stiff and solid through the enlarged contact areas between base and frame which gives a stable stand even with loaded panniers.

Tuned Drive Position

Advanced Hydroforming

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

Frame Safe System

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.

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.

Smooth Welded

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.

Boost148

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 spoke’s wider support in comparison to the 142mm hubs used previously.

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.

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.
