The pictured bike is a sample of a custom bike, which can be yours for just a little extra in the exact colour you prefer. Just reach out and lets start your project.

The Astr RS is designed to tackle the demands of today’s gravel races—rougher terrain, faster speeds, and tougher competition. Its aero-optimized tubing and diffusor fork, inspired by the Falcn RS aero-to-weight study, maximize speed and efficiency.

With a confidence-inspiring geometry—longer wheelbase, slacker head angle, and a deeper bottom bracket—the Astr RS offers unbeatable stability at high speeds. Plus, its generous tire clearance ensures you can run the wide tires needed for rough courses.

By blending optimized aerodynamics, enhanced comfort, low rolling resistance, and lightweight performance, the Astr RS helps racers conserve energy and hit the finish line with more power than the competition.

The Astr RS is built for stability and speed on rough terrain. A 71.5° headtube angle ensures quick handling, while the 74° seat tube boosts climbing and power transfer. Short chainstays allow for tires up to 52mm without sacrificing responsiveness, and a lower bottom bracket adds stability at high speeds. With a lower head height for an aerodynamic position, the Astr RS delivers cutting-edge geometry for competitive gravel racing.

The Astr family has a tyre clearance of 52 millimetres on a 1x setup and 47 millimetres on a 2x setup. Our product developers took this decision because the race terrain is getting rougher and riders feel the need to be armed for this. With this, we confirm our role as a trendsetter in the gravel segment.

Universal Derailleur Hanger (UDH)

The universal derailleur hanger (UDH) is the new standard in the cycling world. Not only is this derailleur hanger compatible with all modern shifting groups, it also protects against derailleur breakage and chain drops. In mountain biking, UDH has long been very common, and Ridley is bringing the technology to other segments as well.
