A PUREBRED DOWNHILL BIKE
The ION G19 is a purebred downhill bike. The GEOLUTION geometry combined with the best suspension components will enable you to reduce your competition times. Over the last 23 years we have been able to gather the experience in countless races that enable us to build the best bikes today. The ION G19 was developed exclusively for downhill sports and we would like to quote our World Cup pilot Jack Reading: “The ION-G19 changes the rules of the game. This new and revolutionary geometry makes the ION-G19 the fastest and safest bike I have ever sat on. That thing is a weapon.” These words show us that we did everything right together with Chris Porter (MOJO UK). The GEOLUTION geometry makes this downhill bike faster and more controllable for the beginner and the professional. With the so-called ET-Key, the steering head angle can be set to 61.5 degrees for fast World Cup courses and 62.2 degrees for shorter and narrower courses. Since only double-bridge forks are used, we have integrated rubber stops on the head tube casting, which simultaneously guide gearshift and brake cables. The high-quality technical ingredients like EC49 head tube, 148mm rear suspension width, 83mm bottom bracket width, oversized down tube and 4-fold sealed industrial ball bearings at all bearing points ensure a light 16.2 kg total weight (L) and that you can have many years of fun.
For each model and each frame size we have designed its own welding device, a so-called frame gauge. Here, the pipe sets and the turned and milled parts fit together precisely, in order to be tacked by our welders at precisely defined points and in exact sequence, and then welded in several passes by TIG (tungsten inert gas) in order to minimize distortion and distortion. Our evenly flat scaled welds are produced by a very slow welding speed and, unlike with applied seams, cause a deep fusion of the material.
ANGULAR CONTACT BEARINGS
The rear triangle of a full suspension bike is not a statically rigid component and is exposed to extreme loads during driving. Critical points are the ball bearings, which ensure low breakaway torque and optimum response of the chassis. In order to extend the maintenance intervals of the frame, Nicolai products rely exclusively on full complement, double-sealed ball bearings.
TOPOLOGY OPTIMIZED STRUCTURE
A bicycle frame and its components are exposed to extreme forces during use. In order to develop a durable, robust but also lightweight bicycle frame, all components are designed at NICOLAI GmbH using topology optimization.
So that you can hit every lane on the trail, we mount a form-fit sliding, exchangeable dropout for track and camber adjustment on all frames. Due to the differently milled, right dropouts for adjusting the lintel, the rear only needs to be slightly readjusted after installation. This takes the strain off the material. The respective lintel height is milled into the RADO with the digits 0, 1, 2 or -1 and -2. After the toe and camber have been set, the RADO is fixed ex works with a pin. This makes the original setting easily reproducible during replacement. This is the only way we can guarantee that NICOLAI products work precisely on the track.
With the ET-Key, the range of application of the frame can be adjusted in a few easy steps. The ET-KEY changes the kinematically active length of the compression strut. With the models ION-G13, ION-G15 and ION-G19 you can adjust the steering angle and the bottom bracket height, e.g. for a visit to the bike park or a steeper trail. With an ION-G16, the shock absorber length can be adjusted via the ET KEY and thus the spring travel can be changed. The damper length/stroke can be changed from 216x63mm to 222x70mm. As a customer you can fully rely on the performance of your Nicolai frame. In the depth of the technology we do our homework and with the introduction of the ET-KEYS we have introduced a robust and simple adjustment technology.
The MUTATOR is a newly developed component on the rear swing arm, which combines many functions in a single component: The mutators are available in different lengths. In this way, only by replacing a mutator can the length of the swingarm “grow with” the frame height according to our GEOLUTION concept. The rear suspension length of the EBOXX E-MTB can also be varied according to customer preference.
Only if the welds are welded deep into the root and have no notches, a bike frame can withstand the impacts from the ground for many years without breaking. Precise riding characteristics are achieved when the rear wheel is precisely straight to the front wheel and even a layman notices that an oblique bike rides strangely (but usually he thinks it’s because of his riding ability).
“GEOLUTION is the geometry concept on which all current Nicolai models are based. In the last 3 years GEOLUTION was developed by NICOLAI and the suspension specialist Chris Porter. 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 GEOLUTION 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.
10 YEARS SPARE PARTS AVAILABILITY
If after a few years of hard work a bearing on a Nicolai frame needs to be replaced, a RADO needs to be replaced due to a fall or a frame needs a new coating, the NICOLAI service staff is the right contact. Since we at NICOLAI manufacture all small parts on our machines, we can also produce spare parts for older models if required. We therefore guarantee spare parts availability of at least 10 years for all Nicolai products.
This product is produced by order , please contact our customer service for details and lead-time. Under normal circumstances, the lead-time takes about 180 days.
