Ridley ASTR Gravel Bike

Ridley ASTR Gravel Bike

​The Ridley ASTR Gravel Bike is engineered to deliver high performance for both avid enthusiasts and competitive gravel riders. Built upon a high-modulus carbon frame, the ASTR offers a lightweight and responsive ride, ensuring efficient power transfer and agility across diverse terrains.​

Key Features:

• Advanced Aerodynamics: The ASTR incorporates an integrated diffuser within the fork crown to minimize air resistance. This design enhances airflow through the fork crown and around the downtube, resulting in reduced drag and improved speed. ​

• Performance-Oriented Geometry: Designed with modern gravel racing in mind, the ASTR features a 71.5-degree head tube angle for responsive handling and a 74-degree seat tube angle to optimize climbing efficiency and power transfer. Short chainstays contribute to a lively acceleration response, while a lower bottom bracket height enhances stability at higher speeds. ​

• Generous Tire Clearance: The frame accommodates tires up to 52mm wide with a 1x drivetrain setup and up to 47mm with a 2x setup, allowing riders to tackle increasingly rugged terrains with enhanced comfort and grip. ​

• Universal Derailleur Hanger (UDH): Equipped with a UDH, the ASTR ensures compatibility with modern shifting systems and provides added protection against derailleur damage and chain drops. ​

• Removable Front Derailleur Clamp: For riders opting for a 1x drivetrain, the ASTR offers a removable front derailleur clamp with a custom cover, maintaining a clean and streamlined appearance. ​
