Its aerodynamically optimized carbon frame, modern gravel racing geometry and premium component package make the ASTR an outstanding choice for competitive gravel racing and fast training sessions.
The combination of SRAM Rival XPLR 13-speed electronic shifting, 50 mm deep DT Swiss GRC1600 carbon aero wheels and wide Schwalbe G-One Evo R tires makes this model particularly appealing to ambitious gravel riders.
The Ridley ASTR shares its modern gravel racing geometry and numerous aerodynamic technologies with the high-end ASTR RS. Its premium HM carbon frame from Ridley's Essential Series combines aerodynamically optimized tube profiles with excellent stiffness and efficient power transfer.
Ridley follows its Aero-to-Weight philosophy, balancing low weight and aerodynamic efficiency to create a fast and versatile gravel racing bike.
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 reduce aerodynamic drag at higher speeds.
One of the ASTR's standout features is the modern SRAM Rival XPLR 1x13 drivetrain. The wireless electronic AXS system delivers fast and precise shifting at the touch of a button and is specifically designed for the demands of gravel racing.
A SRAM Rival XPLR crankset with a 42-tooth chainring is paired with a wide-range SRAM XG-1351 10-46 cassette. The 13 gears provide versatile gearing for fast flat sections, rolling terrain and challenging climbs.
The single-chainring design eliminates the front derailleur, reducing drivetrain complexity and making shifting intuitive even on technical gravel courses.
Another major highlight is the premium DT Swiss GRC1600 carbon wheelset. With an impressive 50 mm rim depth, these wheels are designed to maximize aerodynamic efficiency and perfectly complement the ASTR's racing character.
The deep-section carbon rims help reduce aerodynamic drag, providing advantages particularly at higher speeds. Their 24 mm internal rim width is also well suited to modern wide gravel tires.
These wheels combine the aerodynamic benefits of a deep rim profile with the versatility required for demanding gravel terrain. They are particularly effective during fast races and long high-speed sections where aerodynamic efficiency becomes increasingly important.
The Ridley ASTR comes equipped with 50 mm Schwalbe G-One Evo R tires. These performance-oriented gravel tires provide an excellent balance of low rolling resistance, reliable traction and confident handling across changing surfaces.
The tubeless-ready construction also allows for tubeless installation with the appropriate setup. Running lower tire pressures can improve traction and comfort on rough terrain.
With generous tire clearance of up to 52 mm, the ASTR offers additional flexibility for different tire profiles and individual riding preferences.
The ASTR has been developed specifically for fast gravel racing. A head tube angle of approximately 71.5 degrees provides responsive and precise handling, while the steep seat tube angle of around 74 degrees supports efficient power transfer.
Short chainstays contribute to agile acceleration and quick changes of direction. The lower bottom bracket improves stability at higher speeds, while the low head tube allows riders to adopt an aerodynamic racing position.
The result is a gravel bike that combines road-bike-like efficiency with the control required for fast and technical gravel courses.
The ASTR features a 4ZA Stratos Pro handlebar and Forza Stratos Pro stem with semi-integrated cable routing. This creates a clean cockpit appearance that complements the aerodynamic frame design.
A 27.2 mm 4ZA Cirrus seatpost and Selle Italia Novus Boost Superflow saddle complete the premium component package. Hydraulic disc brakes provide reliable stopping power and precise modulation across changing conditions.
The frame's UDH-compatible derailleur mounting system supports modern drivetrain technology and underlines the bike's forward-thinking construction.
The Ridley ASTR Rival XPLR 1x13 is designed for ambitious gravel cyclists looking for a fast, aerodynamic and well-equipped carbon bike. Its electronic SRAM drivetrain, 50 mm deep DT Swiss carbon wheels and performance-oriented racing geometry make it an outstanding choice for gravel races, fast training rides and demanding adventures beyond paved roads.
