True freedom has a name: Nutrail! It's a bike that holds its line off-road, keeping going where others have long ago had to throw in the towel. CUBE's Nutrail isn't just an on-trend Fatbike - it's also a real CUBE bike with lots of detail that extend its versatility beyond conquering snow-covered winter trails. The high quality and reliability of the RockShox Bluto suspension fork ensures great fat tyre riding practically anywhere, from the Sahara to Alaska. A Fatbike isn't just a bike with extra wide tyres - there are other considerations too. That's why, for the Nutrail, CUBE designed a brand new chassis with special geometry and specific details. The frame is extraordinarily light thanks to CUBE's triple butted and hydroformed High Performance Aluminium (HPA) tubeset. The Nutrail ticks all the boxes for a versatile Fatbike that's ready to take on any trail, blending a tapered head tube, extra-wide PressFit bottom bracket shell and 197 mm quick release axle to create an exceptionally stiff frame. Cutting edge features include cable routing for a Sideswing Direct Mount front derailleur, an replaceable gear hanger and internal cable routing for a dropper post. The 4.5 inch Schwalbe Jumbo Jim tyres and RockShox Bluto RL suspension fork - which was specially developed for Fatbikes - are two of the Nutrail 2X's most important equipment highlights. Taken together, they allow you to ride straight through the winter as well as speed along dry summer trails. 8 mm Answer Fat Atak wheels give the 4.5 inch Jumbo Jims stacks of grip and the handlebar, stem and seat post are all from the CUBE stable of in-house components. CUBE have combined a 2x1 Shimano Deore / XT transmission with a RaceFace Ride 26/24 chainset, and Magura's MT2 hydraulic disc brakes provide reliable speed control even in adverse conditions. Adaptable X12 Hanger - CUBE optimized their new dropout design based on the Syntace X12 through-axle system, enlarging the area of the frame where the hanger is mounted. They 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. Advanced Hydroforming - The 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. Agile Ride Geometry - Cube ran innumerable tests to develop the Agile Ride Geometry in their series of big wheel bikes. Cube 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 them achieve the same trail as their 26in bikes without having to steepen the head angle, thus maintaining generous toe clearance to the front wheel. Secondly they shortened the chain stays without compromising the seat angle. They invented a patented construction to mount the front derailleur to give them more tyre clearance while keeping a conventional seat angle, leading to a perfect riding position for every rider size. Last but not least Cube kept the BB height the same as on their 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 Ultralite - Very high tensile strength heat-treated 75 aluminium alloy is developed for the highest requirements. It is very stiff, fatigue resistant, corrosion resistant and has high elongation. CUBE's Superlite tubes are triple butted, giving very light tubesets with a high level of stiffness. High Performance Aluminium - For CUBE's high end bikes they use High Performance 75 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. 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 CUBE's 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. Frame Safe System - To protect Cube's 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. 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. Wet Paint Surface - On polished, brushed aluminium and all HPC frames, the logos and graphics are applied in multi-layer wet paint. Cube 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. 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.
