All Gravity - No Limits

The new G1 is our ultimate all-gravity machine. It's not only long, flat, incredibly fast and tough, but also highly versatile and adaptable. Whether it's aggressive trail riding or enduro adventures with single crown fork and half shell helmet or bike park action, free racing and DH track with dual crown and full face, the G1 cuts across the established categories. It's the perfect multi-tool for gravity addicts looking for a single bike that can take on any challenge and adapt perfectly to their personal riding style to deliver the best possible riding experience in every conceivable action scenario.

Build Kits And Customizing


Due to the multitude of tuning options, the G1 is not available in a fixed configuration, but is primarily offered as a frame kit that can be completed with an customized build kit by using the order generator on the NICOLAI website. Experienced riders who know exactly what they need and are confident in the world of frame geometries and track- or use-dependent tuning will find the G1 a unique gravity platform that offers them unparalleled possibilities for individual optimization.

Geolution 2.0

The geometry of the G1 is based on our specific Geolution concept. In simple terms, Geolution means that a slacker head angle, longer reach and the associated longer wheelbase make a mountain bike faster, smoother and safer. The steep seat angle ensures a central and comfortable riding position on the bike. This geometry design ensures optimum load distribution between the front and rear wheels. This increases the rider's degree of control in dynamic riding situations and improves the overall handling of the bike. Climbing characteristics are improved as the steep seat angle and long front end position the rider in such a way that the front wheel is prevented from rising on steep climbs.

Size-Proportional Geometry


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.

Mutators - Adaptation And Customization

The seat stay and chain stay lengths of the G1 can be changed by fitting adapters of different lengths, known as Mutators. The bike can therefore be ridden as a 29er, 27.5er or mullet and can be modified accordingly. In addition, the riding characteristics of the G1 can be adjusted in terms of center of gravity, handling, maneuverability and smoothness by installing different Mutators. Mutators also allows the use of two different shock lengths on the G1, which means that the suspension travel can be varied over a wide range due to a 2-position shock mount at the rocker link: When using a 230x65 mm shock, 162 or 175 mm travel is available at the rear. With a 250x75 mm shock, the travel is 182 or 200 mm.

G1 Frame Standards And Interfaces

The frame standards and interfaces have been revised and modernized compared to the predecessor model. The G1 now features a ZS56 head tube, which increases compatibility and adjustment options by allowing the reach, front center and steering angle to be adjusted using optional headset shells. The implementation of the SRAM UDH standard in combination with a 148 x 12 mm thru-axle allows the use of the highly robust SRAM T-Type drivetrains as well as a wide range of other groupsets. The bottom bracket complies with the 73 mm BSA standard. The shift cables and brake lines are routed on the outside of the frame for quick service access and are fixed securely with bolted brackets, while the dropper post cable is routed internally. Many improvements on the new G1 are only noticeable at second glance - but not the design: the slim, polygonal, extra- low top tube with a brace to the down tube and a new seat dome design with integrated clamp already show from a distance: here comes the new one.

Anti-Squat And Anti-Rise

The rear triangle of the G1 is designed based on the Horst-Link concept and has a constant progression over the entire travel. This results in a sensitive response to small bumps for maximum grip and traction, plenty of usable travel with ideal support at mid-stroke and an effective reserve for hard hits and landings. The anti-squat value is 100% in the lowest gear and at 30% sag. This means that the chain pull generated when pedaling induces a rebound movement of the rear end which is equivalent to the compression movement generated when pedaling. This allows the G1 to climb efficiently and accelerate without loss, even as a long-travel bike. The anti-rise value of the G1, which describes the rebound movement of the rear when the brakes are applied, has been reduced even further compared to the previous model and now stands at 62% (30% sag), which means that the suspension remains more active when braking and therefore provides more traction.

EXT Storia V4

Coil Shock

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.

Topology optimization

Computer-aided design to optimize durability, function and weight

In the design of turned and milled parts, we use FEM software (Finite Element Method) to simulate the loads that will occur in later use in order to determine the optimum shape (topology) of these components. Critical areas of the design become visible in this way and can be strengthened by adding material, while material can be saved at less stressed points. In this way, highly complex parts and assemblies can be manufactured that combine maximum durability with minimum weight.


Hollow Milled Technology, load and weight optimized hollow milled volume components

Hollow Milled Technology is a design and manufacturing process that maximizes material and weight savings without weakening the structure when building highly stressed volume components such as the bottom bracket base of the new Nucleon 16. For this purpose, the stress zones in the material are determined by computer simulation during the design phase. Highly stressed areas can thus be strengthened, while material can be saved in areas subject to low stress. This method is called topology optimization. The use of state-of-the-art 5-axis milling machines allows us to manufacture highly complex, hollow-milled frame components from a single piece and to transfer the optimized design with the highest attention to detail.

Insert Bearings

four-fold sealed full-ball groove and angular contact ball bearings

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.

7020 Aluminum

Sustainable and enduring

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.

NICOLAI Welding Technology

Craftsmanship and engineering in perfection

We weld our frames by hand using the TIG process. Our welders are specially trained for this and have many years of experience. For each model and frame size, a precise welding fixture is built, called a frame jig. In it, the CNC-cut tube sets are precisely assembled and fixated with all turned and milled parts of a frame that are to be welded. The frame components are first tacked with single spot welds at precisely specified points in a defined sequence and then, to minimize distortion and stresses, welded in several passes.

Extra Love

powder coating and anodizing colors, decals, customizing, individualization

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.

Warranty and spare parts supply

NICOLAI grants a 5-year warranty on all frame models against breakage and material failure, even in racing use or when jumping. The premise is that the respective models are used within the scope of their designated purpose and are equipped only with the components for which there is an approval. In addition, the manufacturer guarantees a spare parts supply for all models for a period of at least 10 years. Since NICOLAI manufactures all components of its frames itself and on its own machines, in individual cases a subsequent production of spare parts is even possible beyond the period of 10 years.


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.
