Nicolai Argon GX Frame

The Argon GX frame from Nicolai is an excellent base for a fast and smooth gravel or cyclocross bike. It features a Flat Mount brake mount and can be combined with a suspension fork. Large tyre clearance and three bottle cage mounts make it suitable for bikepacking adventures off the beaten track. Fender and pannier rack mounts are there when you need them, but won't stick out if you prefer a cleaner look. The frame is ready for internal cable routing and is thus also compatible with a dropper post. The cable outlet under the bottom bracket is protected from dirt. The additional guide clip at the dropout is a thoughtful detail, as it lays the shift cable sleeve at an optimal angle to the rear derailleur over the last few centimetres. The rather long top tube and the resulting longer reach, combined with a flat head tube angle and longer chainstays, enable you to achieve sporty speeds and enjoy smooth handling with high stability, especially on unpaved ground. Careful weld work makes the frame particularly robust and creates the signature Nicolai weld seams.

Technology:

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.
