Whether it's battling against the clock on a World Cup downhill course or having a blast in the bike park, the Two15 SL is up for it. Despite its burly credentials, this is a bike that's designed to be both lighter than you'd expect and reassuringly bomb-proof - because lighter means easier to handle, which translates to more speed, and more speed is what it's all about... right? Taking their usual no-compromise approach, our designers selected a premium crop of components to give the Two15 SL the competitive edge that it deserves. A Race Face cockpit combines with Sram's GX DH 7 speed transmission and Magura MT7 hydraulic disc brakes to put you firmly in control. Light, tough DT CSW DH 3.7/3.9 wheels wrapped in Schwalbe Magic Marys provide the motive force you'll need, while a Fox 40/49 Float Factory fork and matching Float X2 Factory shock keep the rubber side down, no matter how hard you shred.

Newly updated with a more progressive geometry for 2019 and additional sizes in 29", the principle behind the Two15's frame design is the same succesful four pivot concept that powers all our full suspension bikes. That's important, because it means that we were able to realise the same suspension characteristics as our super-efficient trail bikes, but with plenty of rear wheel travel and noticeably better agility and control than simpler DH bike designs. But we didn't stop with the kinematics, because our engineers also put a lot of effort into reducing weight. The Two15's hydroformed, triple butted tubeset with 157mm rear hub spacing weighs only a bit more than an enduro frame, but delivers extraordinary steering precision and epic rock swallowing capability. And details like the internal cable routing are the icing on the cake, delivering millimetre-perfect gear shifts every time, in even the worst riding conditions. Are you ready to shred? Because the Two15 SL most certainly is...
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.
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.
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
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.
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.
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.
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.
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.
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.
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.
