The Cube AMS is MountainBIKE's Test Winner 3/2012: “The AMS 120 is a great first in the 29er segment for CUBE ... very good acceleration,
the riding position is central and sporty but not too stretched out. Steep uphills are no problem. Featuring superb handling thanks to Agile
Ride Geometry and perfectly equipped for absolute fun on the trails with 120mm of travel. The Syntace X12 rear axle system provides maximum stiffness,
functionality and user-friendly handling. With FOX
32 Float CTD FIT 29 Air fork at the front, FOX Float CTD Boost Valve shock at the rear and Reliable Shimano XT equipment, rolling is stable but agile, curves
are handled easily and jumps are a no brainer. The AMS Race is the Perfect mix of “all mountain feeling” and tour
riding – it all adds up to the verdict of test winner!”
Press Fit BB: 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 to build a wider down tube and more broadly spaced chainstays. Every millimetre of additional width gives a significant improvement in lateral stiffness.
Tapered Steerer: This new steerer tube design is stiffer than a conventional straight steerer and generates a more secure ride feel even in difficult terrain. Minimal flex at the front of the frame means that the greatest possible steering precision is generated. 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.
ARG: Agile Ride Geometry -Three important details lead to the very agile character. Increased fork offsets let Cube achieve the same trail as their 26” bikes without having to steepen the head angle, thus maintaining generous toe clearance to the front wheel. Secondly chain stays are shortened without compromising the seat angle. Cube invented a patented construction to mount the front derailleur to allow for more tyre clearance while keeping a conventional seat angle, leading to a perfect riding position for every rider size. Last but not least BB remains the same as on their 26" bikes. These measures lead to a natural riding position. Every mountain biker will feel immediately at home on a CUBE 29er.
FOX Customised Setup: 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 co-operation with Fox Racing Shox, using extensive
testing for almost every CUBE full-suspension model.
Efficient Ride Control: A very well received development which is used in all AMS models. With Efficient Ride Control particular attention has been given to the fact that irrespective of body size EVERY rider can have the optimum and identical riding experience. Linkage geometry is designed specific to each model so that all frame sizes have the same travel and spring rate curves (STK ). In addition the kinematics have been optimised specifically to travel in respect of sensitivity, drive and no bobbing. For this it was necessary to specially position all rear pivot points. Whether the rider is large or small, with any of these models they will always have the optimum ride experience.
Internal 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.
Aluminium Ultralight: Very high tensile strength heat-treated 7005 aluminium
alloy is developed for the highest requirements. It is very
stiff, fatigue resistant, corrosion resistant and nonshearing.
Our Superlite tubes are triple butted, giving
very light tube-sets with a high level of stiffness.
Advanced Hydroforming: Cube's process can achieve custom shapes and
technical advantages not possible with conventional hydroforming
processes. As this manufacturing method
reduces the number of welds, the weight is reduced
while simultaneously increasing the reliability.
Size Tuned Kinematic: Size Tuned Kinematics is a four-pivot suspension
technology developed exclusively by CUBE. It
guarantees that every frame in every size will have
exactly the same dynamic properties in terms of
wheel travel, axle path and spring rate curve.
Integrated Post Mount: The postmount system removes the need for bolts and the IS adapter, meaning
less parts mean less weight. In this
case we save 30 grams. This may not sound a lot. But as
you see, there is potential to save weight in every detail.
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. Wheel position is controlled 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.
Anodised Surface: The colour of Cube's aluminium frames with eloxal finish
is achieved by anodising, a chemical surface treatment
process. This treatment hardens the surface, making the
aluminium 1000 times more scratch-resistant than before.
Lazer Design Surface: On Cube's high performance aluminium frames,
graphics and text are laser-cut into the material,
making them indestructible for a lifetime.
