ION G1

Behind locked doors these two companies have worked together for over a year to produce a completely bespoke shock absorber and suspension system for the new Nicolai G1. We think that if you want to own the best mtb enduro suspension in the world you should be buying this new bike, the result of our unique collaboration.

Thanks to the increased length versus travel (230×65) in the new metric standard shock there is room for several new technologies which help to give the softest of initial touch (small bump sensitivity), a dynamic ride feel and an unparalleled feedback when the bike is loaded hard. Large spherical bearings in the shock eyelets (seen in all other performance off-road suspension applications) have improved the bump feel and grip in all situations because of the reduced side loading on the shock and they guarantee a long live span of the shock hardware. A negative spring and hydraulic top out system not only enables that all-important soft, initial touch but also allows the rebound to be as dynamic as the rider wants or needs it to be. A hydraulic bottom out system absorbs some of the excess energy normally transferred back to the bike and rider at the limit of their capabilities.

With carefully thought out leverage ratios and damping rates we can accommodate riders of all weights without compromise. A medium sized rider (85kgs) on a medium G1 will be using a 375-425 spring depending on configuration and a XXL rider of 125kgs will be between 550 and 600lbs.

GEOMETRON is the geometry concept on which all current Nicolai models are based. In the last 4 years GEOLUTION was developed by Chris Porter and NICOLAI  The concept is based on the realization that a longer wheelbase, a flatter steering angle and a steeper seat angle make the bike faster, smoother, more climbing and safer.

The geometric relationship between wheels, steering angle, and weight distribution between wheels are the decisive factors for good handling. The relationship between saddle, crank and rear wheel axle are the decisive factors for a good climbing behaviour of a bike. The GEOMETRON concept combines perfect handling with optimum climbing behaviour. The rider is integrated into the bike through the long reach, the steep seat angle and the long wheelbase, so that the centre of gravity lies optimally between front and rear wheel axle.

All GEOMETRON models are driven with short stems, so that the driver has a relaxed, sporty sitting position despite the long top tube.

The very complex topic can be simplified down to 4 advantages which offers both professionals and beginners a clear added value:

• Best climbing ability (front does not rise)
• No feeling of rollover downhill
• The rider sits and stands integrated in the wheel (more control)
• Higher cornering speed (more grip on the front wheel)

These advantages are clearly noticeable not only for the professional, but also for the beginner. We build our bikes because we want to ride them the same way.

We can also produce different rear wheel lengths on different frame sizes. This allows us to take full advantage of our GEOLUTION technology.  The compression struts mutators are installed ex works in the correct length depending on the frame size and wheel size. Changes should only be made by a specialist.

The inner and outer mutator shell is positively connected to the swing arm via a wedge-shaped rectangular structure. This completely prevents twisting or play. The mutator components are both seal carrier and bearing axis.

This minimizes the number of components and thus also the number of error sources.

In order to develop a durable, robust but also lightweight bicycle frame, all components are designed at NICOLAI GmbH using topology optimization. Topology optimization is a computer-based calculation method by which a favorable basic shape (topology) for components under mechanical load can be determined. This text from the textbook abstractly but aptly describes which processes we use to develop new components. In topology optimization, an algorithm calculates the optimized mass distribution in a component based on defined installation spaces, defined forces, material properties and component geometries.

Thus, lighter and stiffer structures can be developed. However, these procedures are only a tool and one of many. However, the most important tool for an engineer is professional experience. The combination of many years of professional experience and computer-based optimization software creates components that are second to none, both technically and optically.

The tensile strength of 7020 compared to 6061 aluminium is about one third higher. The elasticity is about one fifth higher. These properties, coupled with high quality welding, result in a bicycle frame that is far superior to the average in terms of durability.

In comparison to carbon, aluminium is much more robust and tough, so that bottom contact, falls or stone impacts cannot harm the structure.

The wide and flat welded bead distributes force over a larger area, improving the strength of the frame. Sometimes we add gussets to reinforce parts of the frame that receive particularly high forces, such as from braking or jumping.

This extra care and attention to detail ensures that your frame will give you years of fun, even under the most demanding riders and conditions.

These are protected by two additional O-ring seals. Thus, the bearings are optimally protected against moisture and dirt.

Full complement bearings have a higher load rating than standard ball bearings, as a higher number of balls are used in these bearings – in summary, they are more robust.

Frame color:
Powder coated, anodized or factory-raw – you decide what your frame looks like. Powder coating is a melted plastic coating that is significantly more resistant to scratching and impact than conventional coatings.
Lacquer. Anodising is an electrochemical process used to colour the surface of aluminium. The oxide layer is even harder and more scratch-resistant than any powder coating. Additional weight is not applied during anodising. However, the thin oxide layer can be penetrated more easily. With a powder coating or lacquer you can hide flaws in the surface. Scratches, scoring and tool marks can be filled and smoothed like skin folds with make-up. An anodizing does not hide anything, reveals every flaw; the brighter the anodizing tone, the clearer. This is why different colours are produced on welded frames during anodising. However, the current trend is towards frames which are delivered “factory-raw”. The frames are not coated after production, but move directly to assembly. You get your frame without coating (also no clear lacquer). Over time, an oxide layer/patina forms on the frame, causing the shine of the raw aluminium to fade slightly. With the help of a polishing fleece, however, the old shine can be restored in a few easy steps. In addition to the unmistakable look, the “factory raw” look best reveals the manufacturing quality and technical charm of the frame.

Decor:
You can choose between the Nicolai standard lettering or the NICOLAI BIG N logo for the decors. The decors are available in different colours and finishes – you decide.

bellcrank assembly:
You have the choice of adjusting the colour of your bell crank, the tension brackets and the preload covers to your frame. We offer various anodising colours with which you can refine your bike. Due to the process, there may be colour deviations between the components of light anodised colours due to material properties.

Which bike did you ride? What was its geometry? What were your problems with that? Maybe back pain, aching knees or a sting in the neck?

Next we want to know your body measurements and mass, i.e. your height, your stride length, your arm length and your weight. Which seating position do you prefer? Do you have health problems? What do you want to do with the bike? Cross country racing or freeriding? Loose tours or steep trails? Which parts do you want to drive or retrofit later?

Often, after a more precise evaluation of the information, we determine that a series frame can also fulfil your wishes. However, if we notice that our series frames do not meet your requirements, we will design a dimensional geometry for you.
