Ridley ASTR Rival/GX AXS gravel bike with Zipp 303 XPLR carbon wheels and wide-range wireless drivetrain
What Our Gearhead® Experts Are Saying:
"The ASTR keeps me low and aerodynamic even when the route turns rough and steep. The short chainstays and low bottom bracket stay planted where looser gravel bikes start to wander, and the wide cassette means I'm not running out of gears when the climb gets serious."
Why We Like It
We built this around Rival E1 levers and GX Eagle AXS Transmission because the ASTR's race geometry deserves a drivetrain that can follow it anywhere. Rival handles the ergonomics and hydraulic braking on fast sections, while GX Eagle's 10-52T spread keeps the bike moving efficiently when the terrain demands more than a standard gravel cassette offers.
Heads up! We do our best to keep bike specs and images current, but occasional component changes can happen without warning, and sometimes the photos might not show the exact build you'll receive. If you want to double-check the details, our Gearhead® Experts are always here to help.
