All City Bicycles Cosmic Stallion GRX Gravel Bike. We like to get lost, especially if we’re on our drop-bar bike riding down an old fire road or living it up on gravel trails. And if you’re like us, doing so on a modernized steel all-road machine like The Cosmic Stallion GRX makes it all the more interesting. It’s a prime choice that can fly across the tarmac and soak up road chatter from gravel lanes. It’s responsive, fun, and stable, and its A. C. E steel tubing stands out by providing vibration-damping comfort when the roads get rough and tough. The Columbus Futura Cross carbon fork is designed to be secure on uneven surfaces, and it accommodates 12mm thru-axles and flat-mount disc brakes. The Cosmic Stallion GRX features tire clearance for sizes 700c x 47mm or 650b x 42mm (measured without fenders), and it has Di2 routing options for effortless electronic shifting if you’re looking at future upgrades. The current Shimano GRX groupset is a favorite of ours though, offering gravel-specific ergonomics and rugged reliability we can count on.
