The G1-29 Frame by Nicolai for a versatile 29" full suspension bike


The G1-29 frame from Nicolai is a versatile basis for a fast, durable enduro bike that also has its strengths in all-mountain or downhill use. By adjusting the headset and mutators, the frame can be ridden with 27.5" or 29" wheels - mutators for 29" are already pre-installed here. Mutators are screw-in elements that provide fine adjustment and stability at various points on the frame. The 7020-T6 aluminium used for the frame shines with high strength. The thicker down tube and lower top tube give you good legroom, while the round tube design creates a purist look. The GEOLUTION geometry concept delivers traction, safety and speed for unparalleled riding performance. Careful weld work makes the frame particularly robust and creates the signature Nicolai weld seams.

Technology:

GEOLUTION
GEOLUTION is the geometric concept on which all current Nicolai models are based. It was developed by Nicolai and Chris Porter. The concept is based on the knowledge that a longer wheelbase, a flatter head tube angle and a steeper seat tube angle make the bike faster, smoother, safer and more ready to climb. The GEOLUTION concept combines perfect handling with optimal climbing behaviour.
The rider is integrated into the bike by the long reach, the steep seat tube angle and the long wheelbase, so that the centre of gravity is optimally located between the front and rear wheel axle. All GEOMETRON models are ridden with short stems so that the rider has a relaxed, sporty seated position despite the long top tube. This complicated subject can be simplified to 4 advantages, which offer both professionals and beginners a clear added value: best climbing ability (front does not climb), no roll-over feeling downhill, the rider sits and stands integrated in the wheel (more control), higher cornering speed (more grip on the front wheel).

Pressure Strut Mutator
With the help of the compression strut mutator, Nicolai can finely adjust the bottom bracket height and the head tube angle. Mutators are available in the lengths 3.5, 6.5, 10, 12 and 15 mm. This technology enables Nicolai to realise different strut lengths. The added value can be explained as thus: it is possible to mount different wheel sizes on a single G1 frame. It is also possible to realise different rear triangle lengths on different frame sizes. In this way, the advantages of the GEOLUTION technology come into full effect. The compression strut mutators are installed at the factory in the correct length depending on both frame size and wheel size. Modifications should only be made by a specialist.

Swingarm Mutator
The swingarm mutator is also a component on the rear swingarm developed by Nicolai, which combines many functions in just one component: mutators are available in different lengths (33, 41 and 47 mm). In this way, only by exchanging a mutator, the length of the swingarm can " grow" with the frame height according to the GEOLUTION concept. The inner and outer mutator shell is connected to the swing arm by a wedge-shaped rectangular structure, thus totally preventing twisting or play. Mutator components act simultaneously as both seal carrier and bearing axle. This minimizes the number of components and thus the number of component error.

7020-T6 aluminium
Not all aluminium is the same! Nicolai only uses a 7020-T6 (AlZn4.5Mg1) alloy for frames. Compared to 6061-T6 aluminium, this grade offers much better strength. The tensile strength of 7020 compared to 6061 aluminium is about one-third higher. The elastic limit is about one-fifth higher. These characteristics, combined with high-quality welding, result in a bicycle frame that is far superior in terms of durability. Compared to carbon, aluminium is much tougher, so that hitting, falling or stone chipping does not damage the structure.

RADO
To make sure you hit every lane on the trail, Nicolai mounts a form-fitting, exchangeable drop-out on all frames for adjusting the toe and camber. Due to the distinctly milled right dropouts for adjusting the camber, the rear only needs to be slightly readjusted after installation, which eases the strain on the material. The respective camber height is milled into the RADO with numbers 0, 1, 2 or -1 and -2. After the toe and camber have been adjusted, the RADO is fixed with a pin at the factory. This means that the original setting can be easily reproduced when replacing it. This is the only way the manufacturer can guarantee that Nicolai products operate precisely on tracks.

Ich fahre das Bike jetzt seit etwa zwei Monaten und bin einfach nur begeistert.
Zur Verarbeitungsqualität muss man hier glaube ich nicht viel sagen, Herausragend!
Das G1 geht trotz der 160 -170mm Federwegs sehr gut Bergauf und das in einer sehr angenehmen Haltung für den Rücken. Mit meinem alten Bike (Propain Tyee) hatte ich nach langen Uphills immer Rückenschmerzen.
Sobald es Berg ab geht bekommt man das Grinsen dann nicht mehr aus dem Gesicht.
In Kombination mit dem, auf das G1 angepassten, EXT Storia Dämpfer stellt der Hinterbau alles in den Schatten was ich bis dato gefahren bin und da waren schon einige Bikes dabei. (Commencal, Rocky Mountain, YT, Propain)
Was mir beim Aufbau des Bikes besonders viel Spaß gemacht hat ist die Schrauberfreundlichkeit. Leitungen sind bis auf die Sattelstütze alle extern verlegt und sauber geführt, das Tretlager ist geschraubt und für die Aufnahme des Bremssattels gibt es austauschbare Gewindeeinsätze.
Es gibt so viele Clevere Detaillösungen an diesem Rad das man sich den Spaß es selber aufzubauen nicht entgehen lassen sollte!
Zu Nicolai selber kann man nur sagen, großartig das es noch einen Fahrrad Hersteller gibt der alles in Deutschland Entwickelt UND Fertigt.
Zu Bike-Components: Erstklassiger Service! Danke.
