The Ridley ASTR Gravel Bike with Shimano GRX 2x12-speed groupset is a high-performance gravel bike designed for riders seeking speed, stability, and versatility across diverse terrains. Its modern geometry and advanced features make it an excellent choice for both competitive racing and adventurous explorations.
Key Features:
High-Modulus Carbon Frame: The ASTR is constructed from high-modulus carbon, ensuring a lightweight yet robust structure. The frame weighs approximately 1,090 grams (±10%) for a medium size, providing an optimal balance between durability and agility.
Generous Tire Clearance: Designed to accommodate wider tires, the ASTR allows for up to 52mm tires in a 1x drivetrain setup and up to 47mm tires in a 2x configuration. This flexibility enables riders to tackle increasingly rugged terrains with confidence.
Performance-Oriented Geometry: The bike features a 71.5-degree head tube angle for responsive handling and a 74-degree seat tube angle to enhance climbing efficiency and power transfer. Short chainstays and a lower bottom bracket contribute to increased stability at high speeds, while a reduced head tube height promotes an aerodynamic riding position.
Integrated Fork Crown Diffuser: An innovative diffuser integrated into the fork crown reduces aerodynamic drag by improving airflow around the downtube. This design allows air to pass more easily through the fork crown, resulting in less resistance and increased speed.
Shimano GRX600 2x12-Speed Groupset: The ASTR is equipped with the Shimano GRX600 groupset, offering precise shifting and reliable performance tailored for gravel riding. The 46-30T crankset paired with an 11-36T cassette provides a wide gear range suitable for various terrains.
4ZA Breva Wheels and Vittoria Terreno Tires: The bike rolls on 4ZA Breva 21TL wheels, complemented by Vittoria Terreno Dry TLR 700x47c tires. This combination ensures optimal traction and control across different surfaces.
Deda Components: High-quality Deda components, including the Super Zero Gravel Alloy handlebar and Super Box stem, enhance the bike's ergonomics and control, contributing to a comfortable and efficient riding experience.
