ASTR Gravel Frameset

What Our Gearhead® Experts Are Saying:

"Building up the Astr frameset was a reminder of how refined Ridley’s gravel engineering is. The shorter chainstays, steep seat angle, and lower BB height create a performance-focused feel that accelerates fast and holds a line over rough ground. With UDH, big clearance, and a removable FD mount, the frame is incredibly easy to configure for racing—or for a lightweight, fast adventure build."

The Ridley Astr Frameset is engineered for riders who demand speed and precision across every gravel discipline. Ridley applies its aerodynamic-to-weight design principles to a modern gravel geometry, giving the Astr both the snappy acceleration of a race bike and the stability needed for unpredictable surfaces. The combination of a steep seat tube, a balanced front end, and compact chainstays creates a powerful pedaling platform that delivers efficient climbing and sharp handling without sacrificing comfort on long days.

At the technical level, the Astr’s HM carbon layup maximizes stiffness in key load zones while absorbing the smaller vibrations that dominate mixed terrain. The integrated fork-crown diffuser contributes to improved airflow, and the D-shape steerer enhances steering precision. Wide tire clearance—up to 52mm with a 1x drivetrain—opens the door for aggressive race setups, endurance versatility, and confident traction on loose surfaces. With both 1x and 2x compatibility, a removable front derailleur clamp, and Universal Derailleur Hanger alignment, this frameset integrates seamlessly with today’s most advanced drivetrains.

Designed around a BB86 bottom bracket and 700c wheels, the Astr supports a broad ecosystem of performance components. Riders can pair it with lightweight carbon wheels, modern gravel drivetrains, or aerodynamic cockpits to tailor the frame to specific race scenarios or long-distance events. Whether you’re pushing for speed on smooth dirt or diving into technical backcountry routes, the Astr is built for competitive gravel riders who want stiffness, compliance, and configurability in equal measure.

Heads up - We do our best to keep bike specs and images current, but occasional component changes can happen without warning-and sometimes the photos might not show the exact build you'll receive. If you want to double-check the details, our Gearheads are always here to help.
