Vélo Gravel Ridley ASTR Shimano GRX800 Di2 2x12v AST02As(M) Black Metallic Bronze Gold

The ASTR Shimano GRX800 Di2 2x12v Black Metallic Bronze Gold Ridley is a gravel bike designed for cyclists looking for a fast, modern model capable of tackling all types of terrain. Directly inspired by the high-performance ASTR RS, it incorporates the ‘aero-to-weight’ principles developed by Ridley to combine aerodynamic efficiency, lightness and stability.

Its carbon frame features performance-oriented geometry with a more aggressive riding position, a lowered bottom bracket for greater stability at high speeds, and short chainstays that maintain excellent responsiveness during acceleration. The diffuser integrated into the fork crown also improves airflow to reduce drag and maximise efficiency on fast sections.

Fitted with the Shimano GRX800 Di2 2x12-speed groupset, this ASTR guarantees fast, precise and reliable gear changes whatever the conditions. Its compatibility with tyres up to 47 mm in 2x drivetrains enhances comfort, grip and control on the most demanding routes.

With its particularly elegant Black Metallic Bronze Gold colour scheme and its design geared towards modern gravel racing, the Ridley ASTR offers the perfect balance between speed, versatility and control on the terrain.
