The Ridley ASTR RS Force XPLR 1x13 is engineered for maximum performance in modern gravel racing. As the high-end model of the ASTR family, it combines an exceptionally lightweight and aerodynamic Elite Series carbon frame with progressive racing geometry and premium components. SRAM Force XPLR 13-speed electronic shifting with an integrated power meter, ZIPP 303 XPLR S carbon wheels and the integrated Forza Nimbus Pro carbon cockpit make this gravel bike a true racing machine.
At the heart of the ASTR RS is Ridley's premium Elite Series carbon frame. Weighing approximately 890 grams in size M (unpainted), the frame is exceptionally lightweight for a performance-oriented gravel racing bike. Ridley achieves this through a carefully optimized carbon layup using premium Toray carbon fibers.
A combination of 24T, 30T, 50T and 60T carbon allows stiffness, comfort and weight to be precisely balanced in different areas of the frame. The result is a lightweight, responsive construction that delivers efficient power transfer and confident handling.
The development of the ASTR RS follows Ridley's Aero-to-Weight philosophy. Instead of focusing exclusively on low weight, Ridley combines an exceptionally lightweight frame with advanced aerodynamic optimization.
Specially shaped tube profiles help reduce aerodynamic drag, delivering aerodynamic performance comparable to the Ridley Kanzo Fast. At the same time, the ASTR RS remains impressively lightweight, making it particularly effective on fast gravel courses with varying elevation profiles.
One distinctive aerodynamic feature is the carbon fork with an integrated diffuser in the fork crown. This design improves airflow between the fork and down tube, helping to minimize aerodynamic resistance.
One of the standout features is the premium SRAM Force XPLR AXS 1x13 drivetrain. This wireless electronic system delivers fast and precise shifting at the touch of a button and is specifically developed for the demands of modern gravel racing.
The SRAM Force XPLR crankset features a 42-tooth chainring and an integrated spindle-based power meter. This allows riders to accurately monitor their power output during training and racing, making it an excellent tool for structured training and effective pacing.
A SRAM XG-1371 10-46 cassette provides a versatile gear range for fast flat sections and challenging climbs. The SRAM Force XPLR rear derailleur ensures precise shifting and reliable chain management even on rough terrain.
The Ridley ASTR RS comes equipped with premium ZIPP 303 XPLR S carbon wheels. Specifically developed for gravel racing, these wheels combine aerodynamic efficiency with a rim profile optimized for wide gravel tires.
The wide carbon rims are designed to work together with suitable gravel tires to reduce aerodynamic drag and improve efficiency across different surfaces. Their wide profile also supports the tire shape, helping riders find the right balance between grip, comfort and rolling resistance.
The ZIPP 303 XPLR S wheelset perfectly complements the racing character of the ASTR RS and provides an excellent foundation for fast and demanding gravel competitions.
Another highlight is the premium Forza Nimbus Pro integrated carbon cockpit. This one-piece handlebar and stem system creates an exceptionally clean front end and integrates seamlessly into the aerodynamic design of the ASTR RS.
Integrated cable routing minimizes exposed cables and supports aerodynamic efficiency. At the same time, the carbon cockpit offers performance-oriented ergonomics and precise control on fast gravel courses.
Despite its aerodynamic racing focus, the Ridley ASTR RS offers impressive tire clearance of up to 52 mm with its 1x13 drivetrain. This makes it perfectly suited to modern gravel racing, where wider tires are becoming increasingly important.
The bike comes equipped with 50 mm Vittoria Terreno T50 tubeless-ready tires. These combine efficient rolling characteristics with reliable traction and control on changing surfaces. The generous clearance also provides flexibility for different tire choices and race conditions.
The ASTR RS features modern geometry designed for high speeds and demanding gravel terrain. A head tube angle of approximately 71.5 degrees and a steep seat tube angle of around 74 degrees combine precise handling with efficient power transfer.
The longer wheelbase and lower bottom bracket improve stability on fast and technical descents. Meanwhile, short chainstays contribute to responsive acceleration, and the lower head tube allows riders to adopt an aerodynamic racing position.
The Ridley ASTR RS Force XPLR 1x13 combines advanced carbon technology, aerodynamic efficiency and uncompromising premium components. Its lightweight Elite Series frame, electronic SRAM Force drivetrain with power meter, ZIPP carbon wheels and integrated carbon cockpit deliver everything ambitious gravel racers need to perform at their best.
