Mosaic AR-1
The AR-1. The ultimate all road bike. Or maybe just the ultimate bike.
The Mosaic AR one is no doubt the most capable bike we've ever produced. It will extend road rides well past where the pavement ends and, at the same time, do double duty as a fast gravel rig.
To achieve this, we've taken the proven Mosaic GT-1 AR and further modernized it with an ENVE In-Route integrated cockpit, our in house designed Zero Ops IS52 head tube and a T47 bottom bracket for a seamless front to back brake integration. While still accommodating a traditional 2X road group set the AR-1 boasts tire clearance to a generous 40mm while retaining the legendary handling characteristics that the previous GT-1 AR has become so loved for. More than a road bike, not quite a big tire gravel bike, the GT-1 AR truly defines its own category.
Utilizing ENVE's Integrated Allroad Fork and the Mosaic Allroad chainstay design, the GT-1 iAR has the same intuitive feel as our GT-1 AR, bringing confident & stable handling on mixed terrain, the comfort to ride as long as you're willing, and the freedom to take absolutely any road you please, regardless of its surface. As every Made to Order Mosaic frameset, this is all delivered via rider-specific selection of double-butted titanium tubing that is infinitely customizable depending on your fit requirements, ride preferences, and build configuration.
New for 2026, the AR-1 is available in standard size and finish through our batch built program, check our batch built page for size availability.
