Ridley ASTR Gravel Bike Shimano GRX600 2x12-speed AST02Bm 2025

With the launch of the little brother to the RS version, Ridley is reaffirming its ambition to offer everyone the chance to own an ASTR. Sold at an affordable price, this bike features a high-quality carbon frame. It features modern geometry to give you greater stability on trails, as gravel riding is typically done at higher speeds and over rougher terrain. The seat tube is also steeper to provide maximum power transfer and improve your performance. In addition to major aerodynamic improvements, this bike offers 47–52 mm tyre clearance to fit wider tyres for greater grip and comfort.

In addition to this high-quality frame, the Ridley ASTR AST02Bm is equipped with reliable components. The Shimano GRX600 groupset offers precise and fast gear changes, as well as high-performance disc braking in all conditions. The 4ZA Breva 21TL wheels deliver excellent performance on all terrains. Thanks to these qualities, this Ridley ASTR AST02Bm will be your perfect companion on every adventure, whether on trails or on the road.
