Frame Nicolai ARGON GX

ARGON GX

A gravel bike’s potential should shine on asphalt as well as on gravel and in light off-road terrain. The decisive factor here is correctly placing the bike along the wide spectrum from road performance to off-road capability, the bike wants to set the pace and the range that it can optimally cover. A gain in off-road performance through wider tires and a more upright riding position goes hand in hand with a loss of road speed and range due to higher air volume and rolling resistance. If, on the other hand, the focus is set more towards the road, narrower tires quickly reach their limits off-road and a front-heavy riding position makes handling more difficult. A classic conflict of objectives, in which NICOLAI’s Argon GX shows new and very interesting solutions. The Argon GX is a new addition to the Argon family, which includes lightweight NICOLAI hardtails and classics such as the Argon CC, Argon FR and Argon Road. The name comes from the gas argon, which is used as an inert protective atmosphere when welding the frames. GX stands for Gravel plus Cross.

CRAFTSMANSHIP AND ENGINEERING

YOU CAN ALWAYS RECOGNIZE A NICOLAI BY ITS WELDED SEAMS

A NICOLAI bike is easily recognizable even without branding, its characteristic scaled welds and the machined aesthetics of the milled parts. Nothing is sanded down or concealed. The industrial design language is not an end product in itself. It reflects the product’s development process, shows off the design logic and reveals its properties and functions. This not only creates trust in the product, in its quality and durability, but also ensures a highly identifiable brand with a constantly growing and loyal fan community.

Welding is done by hand using the TIG method by specially trained welders with many years of experience. For each model and frame size a precise welding jig is built, the so-called frame gauge. In it, the CNC-cut tube sets with all turned and milled parts of a frame that are to be welded are precisely assembled and fixed.

The frame components are first tack-welded with individual spot welds, welded at precisely specified points in a defined sequence and then, to minimize distortion and stresses, welded in several passes. The uniformly flat-shingled weld seams so characteristic of our brand are produced by a very slow welding speed. This results in deep fusion of the material and large-area dissipation of the loads and forces occurring in the frame.

HOLLOW MILL

MILLING ART / ORGANIC SHAPES

NICOLAI manufactures all frame components and tube sets of the Argon GX in its own German factory. In addition to its many years of experience, the manufacturer relies on topology optimization during the design process, a computer-aided simulation of the forces that will be found in the real world. This process enables the construction of particularly durable but lightweight components and assemblies. Thanks to modern 5-axis CNC machines, there are virtually no limits to NICOLAI’s ability to produce complex, optimized 3D milled parts. Particular characteristics found on the Argon GX such as the seat stay yoke or the combined bottom bracket/chain stay yoke are made possible by our so-called ‘Hollow Mill’ technology.

Welded at NICOLAI by experienced hands in several passes at a very slow speed to achieve a deep fusion of the material, minimizing stress and distortion. The iconic flat and even scaled welds on the Argon GX are not only visually impressive, above all they optimally dissipate the forces placed on the frame. The manufacturer has complete confidence in its designs because where most gravel bikes limit the total weight of rider and bike to 125 kg, the Argon GX frame has no weight limit and a 5-year warranty that includes the toughest uses and competitions.

The Argon GX is designed to be torsionally stiff, which means that the pedaling force is converted directly and efficiently into propulsion. 142 x 12mm thru axle dropouts further strengthen the frame construction. On some Gravel bikes, flexible rear stays are installed or elastomers are glued into the frame to gain some comfort, NICOLAI does without such features. Durability and an efficient drive are clearly the top priorities here. NICOLAI sees wider tires as the prime factor for ride comfort and the rear triangle of the Argon GX provides ample clearance. A short seat tube in relation to the frame size allows a longer extension of the seat post, which further increases seated comfort with more flex.

TIRE WIDTH IS A CORE FACTOR

MORE GRIP, MORE SAFETY

The frame of the Argon GX is made of 7020-T6 aircraft aluminum not only for comfort through absorption and self-damping, especially considering the off-road capability of a gravel bike, the tires are an important core factor. The wider the tires, the lower the air pressure that can be run without risking a puncture, lower pressure means a larger contact patch for the tire off-road increasing grip and safety. The Argon GX can accommodate tires up to 45mm wide on 28 inch wheels or 50mm wide on 27.5 inch wheels, putting it at the upper end of the scale compared to other gravel bikes.

TRIPLE BOTTLE CAPACITY

BACKPACK, HIPPACK OR CLASSIC BOTTLE HOLDER?

The decision is yours. The ARGON GX has three bottle cage mounts in all frame sizes from S to XXL. From now on we can also deliver your NICOLAI directly with the NICOLAI x FIDLOCK water bottle. With the 0.6 liter TWIST bottle, Fidlock sets standards for optimally functioning drink bottles.

The bottle can be intuitively snapped onto the down tube without an ugly plastic or metal cage via magnets with a twisting motion. Jumps or rock gardens can not dislodge the bottle. Rattling or lost bottles are a thing of the past.

PINION OPTION

CONTROLLED PERFORMANCE

Many NICOLAI models can be equipped with a Pinion GmbH gearbox on request. The transmission is low-maintenance and optimally integrated into the bicycle frame. The central centre of gravity and the lighter rear wheel bring noticeable advantages in handling, driving dynamics and rear-end performance. The transmission reacts to shift commands at lightning speed. The Argon GX PI will be available from May 2021.

CABLE HOUSING AND ROUTING

TECHNICAL AESTHETICS

The cables and lines on the Argon GX are routed via minimalist, screwed guide clips in the down tube so the bike appears clean and tidy, which further emphasizes the technical aesthetics of the frame. There are multiple options at the front of the down tube on both sides. This allows for a variety of routing options including routing for a Shimano Di2 electronic shifting system and for a dropper seatpost.

The exit of the housings under the bottom bracket is protected by a cover from dirt and water. How far NICOLAI thinks in detail, is also evident in the rear derailleur cable guide: an additional guide clip, which is bolted to the dropout, guides the shift cable housing at the optimum angle for shifting precision to the rear derailleur. At the same time, the housing is tightly secured to the frame and protected from damage.

BRAKES

FLAT MOUNT 140

Like mountain bikes, gravel bikes are equipped with disc brakes. This ensures a sensitive dosage of braking force with a constant pressure point regardless of dirt and weather. The Argon GX uses the new Flat Mount 140 standard, which allows a particularly compact, lighter brake design.

7020-T6 ALUMINIUM

NOT ALL ALUMINUM IS THE SAME

The frame of the Argon GX is made from 7020-T6 aircraft aluminum (AlZn4.5Mg1), which has a 30% higher tensile strength and a 20% higher elastic limit compared to the 6061-T6 alloy (AlMg1SiCu) commonly used in frame construction. Compared to lighter carbon frames, an aluminum construction can have a weight disadvantage, but is generally less sensitive to stone chips and crash damage.

GEOMETRY

FROM XS TO XXL

The geometry of the Argon GX combines sportiness and efficiency with control and handling across a wide range. The recipe for this is a relatively long top tube and reach dimension for efficiency and speed in combination with a slack steering angle and a longer rear for smoothness and driving stability on dirt roads and trails. The frame is also compatible with gravel suspension forks up to 40mm travel, which NICOLAI offers as an upgrade option. NICOLAI applies adaptive geometry to the Argon GX, which takes into account weight and proportion for different body sizes. As the length and height of the main frame increases, the seat angle becomes flatter on larger frames, while the steering angle becomes steeper. This ensures that the bike’s characteristics remain the same at each size. The Argon GX is offered in 6 frame sizes, from XS to XXL, suitable for riders from 155cm to 208cm. Few manufacturers offer such a wide range.

RADO

REAR ALIGNING DROPOUT

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.

COLOR VARIETY

EXTRALOVE

With a NICOLAI frame you determine the design. Every Nicolai frame can be produced in a color according to your preferences. NICOLAI operates its own powder coating facility at the factory and offers a choice of over 50 colors for the Argon GX, each in high gloss or satin finish. However, the frame can also be optionally hard anodized, with a choice of black, bronze and titanium. On request, the frame can also be supplied uncoated in the “factory raw” aluminum finish.

ADVENTURE BIKE PACKING

RACK & FENDER

Multi day bike tours through remote areas are very much in vogue, and more and more bikers would prefer to experience their adventure on a fast, lightweight gravel bike instead of a classic touring bike. The Argon GX has all the mounting points for mounting mudguards and pannier racks. NICOLAI has succeeded in hiding these so discreetly that the look of a purebred gravel sports bike is not affected. The mounting threads for mudguards on the dropouts and inside of the yokes you discover only with a closer look.

For the installation of a strong rear panier, NICOLAI offers an adapter, which is inserted into a transverse cutout of the seat stay yoke and screwed through two holes located on underneath. The Argon GX has 3x bottle cage mounts in all frame sizes. A bracket under the down tube can be used for mounting a toolbox, for example. The front triangle is ideal for mounting frame bags thanks to straight-cut trapezoid shape.

The possibility of carrying equipment naturally includes roadworthy bags and packs which make the Argon GX very attractive as a fast commuter and everyday bicycle.

FRAME SIZE AND TAILORMADE

WE MANUFACTURE YOUR CUSTOM-MADE FRAME

You can order, pay and pick up your custom frame directly from us or from your Nicolai dealer. For technical details we are directly at your disposal. First we need to know why you want to ride a custom frame. Mostly the reasons lie in the past.


MANUFACTURING QUALITY

MADE IN GERMANY

The manufacturing quality itself is not yet an added value for a customer. The following two added values “durability & precise driving characteristics”result from production quality. 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).

WARRANTY AND SPARE PARTS SUPPLY

We provide a 5-year warranty on all frame models against breakage and material failure, even for competitive use and jumps. The prerequisite is that the respective models are used within the scope of their designated purpose and have only been equipped with components for which an approval has been obtained. In addition, we guarantee the availability of spare parts for all models for a period of at least 10 years.

CUSTOMIZATION AND CONFIGURATION

NICOLAI offers the Argon GX as a custom build, where you can choose from various components and finish options via an online configurator to assemble a bike according to your own requirements and dreams.

If the Argon GX is to be used mainly on road and gravel and occasionally on trails, characteristics closer to a road bike are desired, the choice of a 28″ wheelset with 32mm wide Continental Cross King tires is recommended, for example. In terms of gearing, the new Shimano Gravel group GRX with 2 x 11 gears and a fine gradation would then be the ideal drivetrain. 

At the other end of the spectrum, however, the Argon GX also offers a configuration that comes pretty close to a hardtail mountain bike, with SRAM Force Eagle 1 x 12 gears and 27.5 x 2 inch tires. The installation of a lowerable seatpost (dropper post) is possible along with the installation of a straight MTB handlebar or the equipment of a suspension fork.

When configuring the components, it should be noted that the gears are a limiting factor in the choice of tire width. When using a front derailleur for a 2 x 11 Shimano GRX circuit, the cage of the derailleur allows a maximum tire clearance of 42 mm. This limitation is not Argon GX specific, but affects all bikes equipped with a dual GRX shifting.

The fork of the Argon GX can also be selected according to the mode of use. The tapered standard head tube with semi-integrated bearings can accommodate either a rigid gravel fork or a gravel suspension fork with up to 40mm travel.

The choice of seatpost also allows NICOLAI customers to perfect the Argon GX according to their own personal definition of gravel biking. The seat tube’s inner dimension of 31.6mm allows the use of a regular rigid seat post as well as the installation of a dropper post. On mountain bikes this has long been the standard, so loose terrain, steps and steep descents on a Gravel Bike can horrify a rider accustomed to a dropper post.

Consequently, with the Argon GX you have the choice between a gravel drop bar (wide, flat, and curved racing handlebar) or a straight mountain bike handlebar.

No matter where the rider puts his personal focus and how the individual custom project looks in the end, the Argon GX does not limit you to a narrowly defined range of use. Even with a suspension fork, wide tires and straight handlebars, the sporty geometry and stiff frame make for fast road riding. If the build is closer to a road racing machine, most off-road trails are still open to you thanks to the smooth ride and safe handling. The Argon GX provides a broad and solid base for any definition of gravel biking.

Delivery time for frames to order is 10 weeks.

Due to the variability of the configuration of NICOLAI frames, it is necessary to tune the exact specification by phone and email!
