A bike built for total performance or riding along with friends

Whether you want to go on an adventure or simply go for a casual ride, the Radon is the bike for you. Based on the Krypton’s geometry, it’s our unique solution to a fundamental problem: giving the bike enough stiffness to make it race-worthy while keeping it comfortable and stable enough for recreational cycling. It’s tire clearance gives you more comfort, and the 3D system allows more positioning options and superior stiffness.

The symbiosis of versatility, durability and comfort. A stylish look, a unique experience.

The Radon is a perfect bike for me! It allows me to benefit from the quality and expertise of Argon 18 while having a comfortable bike that is designed for fun.
