True freedom can only be experience when you're willing to try a new direction. The Nutrail Hybrid is the perfect tool for the job. With 4.0 tyres and powerful Bosch CX drive it quite simply knows no limits, rolling on with nonchalent ease whether you're out in the sticks or in the thick of the urban jungle. This CUBE masterpiece - with a brand new aluminium frame - contains all of our know-how and fastidious attention to detail. It's these high quality features that have produced a Fat e-bike that blends the fun factor with genuine everyday practicality.
We faced two challenges in designing the Nutrail Hybrid. On the one hand, we set out to build a top class Fatbike that would be at home on trails and fun to ride both every day and on longer adventures. And on the other, we needed to perfectly integrate the Bosch drive and all of its specific requirements. It wasn't easy, but we got there in the end by sweating the details. Triple butting, hydroforming and clever design make for a frame that's extremely light, with precision handling. The tapered head tube and 177mm rear axle provide even more rigidity. We positioned the drive and battery for optimum performance and this, combined with our Agile Ride Geometry, guarantees faultless handling. Luggage rack mounting points give the Nutrail extra practicality for day-to-day use. And, of course, we've used StealthReady to make it dropper post-friendly.
For limitless adventure and new experiences, the new Bosch CX Drive Unit is an absolute must. This e-drive, with its 75Nm of available torque and 600W power output, is the best-performing drive currently available. Combined with a 500Wh battery, the range is impressive. Schwalbe's 4.0 inch Jumbo Jim tyres provide traction on any surface, regardless of whether you find yourself on a steep trail, loose rocks, snow or sand. And Shimano's new 11 speed XT transmission, with its 11-42 tooth cassette, provides an incredible gear range to tackle even the steepest of mountain trails. Rock Shox's Bluto suspension fork, specially developed for Fatbikes, transforms the Nutrail into a comfortable, ultimately versatile trail-taming machine that will turn any ride into a new experience.
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.
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.
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.
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.
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.
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.
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
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.
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.
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.
