Ridley Astr RS Force XPLR 2025
The ASTR RS is a performance gravel bike developed for modern gravel racing. Recently, these races have become increasingly rough, while riders are going faster than ever, leading to new demands on the bike.
The Astr RS uses aero-optimized tubing and a diffusor fork based on our Falcn RS aero-to-weight study. Additionally, the Astr RS has a confidence-inspiring geometry with a high degree of stability at high speed (longer wheelbase, slacker head angle, deeper BB). The large tire clearance allows fitting the tires required to handle rougher courses.
Riders need to be able to conserve more energy during the race: optimized aero, more comfort, less rolling resistance due to the wider tires, and better climbing performance due to the low weight mean racers will go into the final with more energy in the tank than their adversaries.

Tire clearance up to 52 millimetres
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.
Performance geometry
Modern performance geometry demands more stability due to increasingly rough terrain combined with higher speeds. A 71.5-degree headtube angle ensures you have faster handling. The Astr family features a steeper seat tube (74 degrees), improving climbing performance and power transfer.
The product developers kept the chainstays as short as possible to accommodate tyres up to 52 millimetres without losing the feeling of responsiveness when accelerating. In addition, the bottom bracket is a bit lower. This ensures you have more stability at high speed. Finally, the head height is lower, so you sit more aerodynamically on the bike. In summary, this boils down to a modern competitive geometry, tailor-made for the ambitious gravel racer.
Aero-To-Weight
The focus in the road bike market used to be on stiffness versus weight, but has recently shifted to the balance between aero and weight. Ridley decided to combine the best of both worlds with the Astr, which means it has been made as aerodynamic as possible without sacrificing the bike's weight. The Astr has a similar aero performance to the Kanzo Fast and weighs just 890g (in size Medium), meaning cyclists no longer have to choose between lightweight and aero.
Diffuser fork crown
The fork crown has an integrated diffuser to reduce drag. The airflow passes more easily through fork crown while extra energy is added to it. The result is that the airflow passes the downtube more easily without pushing the bike back. At the same time there is less drag in the area behind the fork and headtube.
Less resistance, more speed!
