The ASTR RS is a performance gravel bike developed for modern gravel racing. Recently, these races have become increasingly rough, while riders are going faster than ever, leading to new demands on the bike.

Features

• The Astr RS uses aero-optimized tubing and a diffusor fork based on our Falcn RS aero-to-weight study. Additionally, the Astr RS has a confidence-inspiring geometry with a high degree of stability at high speed (longer wheelbase, slacker head angle, deeper BB). The large tire clearance allows fitting the tires required to handle rougher courses.
• Riders need to be able to conserve more energy during the race: optimized aero, more comfort, less rolling resistance due to the wider tires, and better climbing performance due to the low weight mean racers will go into the final with more energy in the tank than their adversaries.
