G1

From S to XXL, the geometry of the G1 has now been proportionally optimized to ensure consistent weight distribution, handling and responsiveness across all frame and body sizes. We would like to point out that a truly proportional geometry has been created here that goes far beyond the usual increase in chainstay length. Among other things, the steering angle and seat angle change depending on the frame size. This ensures that an optimum balance is maintained between the front center and rear center. A constant, balanced ratio of reach and stack is also important in order to guarantee a consistent load distribution on the front and rear wheels. Only a loaded tire can generate traction on different surfaces. An uneven wheel load quickly leads to understeer or oversteer. The geometry data of the different frame sizes, which at first glance appears arbitrary, is therefore no coincidence, but the result of extensive calculations and tests. The result is an outstanding bike handling that offers both rookies and experienced riders maximum performance, control and confidence, regardless of body and frame size.

At the heart of the G1's rear suspension is the brand new EXT Storia V4 coil shock, which was developed by EXT in cooperation with our brand and GEOMETRON and has been custom-tuned for the G1. With the G1 this shock is available for the first time on a production bike. The EXT Storia V4 delivers a particularly sensitive response, temperature stability and a progressive, hydraulic bottom-out protection that works independently from compression damping, effectively preventing the suspension from bottoming out. In addition, the Storia V4 also has a hydraulic top-out system, which builds up hydraulic resistance towards the end when the suspension returns to its unloaded state, effectively preventing an undamped top-out clunck when the shock is fully extended.

The rear end of a full-suspension bike is subjected to high dynamic loads during riding. The focus here is on the bearing points where the forces are transmitted between the components. The full-ball, double-sealed bearings installed on our frames are made by the ENDURO brand. They not only have top marks for power transmission, but also a particularly low breakaway torque, which ensures sensitive, smooth suspension response. At the same time, they offer the best possible sealing against dirt and moisture for a long service life and long maintenance intervals.

All our frames are manufactured from 7020-T6 aircraft grade aluminum, because we are convinced that this alloy is the superior material in the construction of mountain bikes. Compared to the 6061-T6 (AlMg1SiCu) alloy commonly used in bicycle construction, 7020-T6 (AlZn4.5Mg1) has about 30% higher tensile strength and about 20% higher elastic limit. The widespread use of 6061-T6 aluminum in frame construction is due in part to the fact that it can be processed at lower tooling costs and frames can be straightened after welding with less technical effort. Our frames are engineered and designed so that when overloaded, deformation occurs in a defined area of the frame rather than breakage, significantly reducing the risk of serious accidents and injuries. A NICOLAI aluminum frame is designed to withstand many years even under tough competition conditions.

Thanks to a wide range of colors, every NICOLAI frame can be customized as desired. In our factory's powder coating facility, we process more than 50 colors, each of which can be applied in a high-gloss or satin finish. A separate color is possible for each welded frame component. Frames and frame components can also be anodized as an option, with a choice of black, bronze or titanium. An extended range of anodized colors is available for turned or milled applications such as bell cranks, bearing caps or cable clips, allowing color matching with common components, for example. We also offers an uncoated aluminum finish as "factory raw". If you then add the range of decals colors, the number of design options is almost limitless and a unique, personalized custom bike is guaranteed.

We have developed an elaborate reusable bike box for our mail-order shipping. In it, the new NICOLAI bike arrives protected in a wooden frame and guaranteed safe at the customer and is ready for use after a few simple steps. The same box is reused when the bike is returned to us for repair or service. All shipping protections of the bike box such as pads, lashing straps, brackets and screw connections are also reusable.
