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.
