The GT-1 AR is tailored for uncompromising excellence on tarmac, broken asphalt, dirt roads and gravel.

The GT-AR Series is tailored for uncompromising excellence on tarmac, broken asphalt, dirt roads and gravel. The AR represents Mosaic's All Road model, and these machines epitomize the fusion of road bike agility and off-road resilience---the very core of the G-Series philosophy.

Short chainstays and a steep head tube angle mirror high performance road geometry, while a lower bottom bracket, slightly longer wheelbase and room for 700x38c tires extend the AR’s sweet spot well into the dirt realm. These bikes give the rider confidence to tackle a wide variety of terrain and surfaces ranging from straight-up pavement to fire roads and light gravel – all without sacrificing road bike speed, responsiveness and handling.

Custom rider specific sizing comes standard with the GT-1 AR and we use rider-specific, lightweight butted titanium tubeset in smaller diameters to give the AR a lively, compliant ride when compared to the oversized tubes we use for the R-Series or GT-45’s. Optional fender and rack mounts make the GT-1 a perfect bike for year round riding, and it’s also available as a fully integrated cable model—the GT-1 iAR.

Geometry

Rider Specific Geometry

With a fit-first design approach, custom geometry is drawn up based on bike fit information provided by you and your Mosaic Dealer. Taking into account each rider’s aspirations and use case for the bike, we continue to fine-tune the design to culminate in a riding experience and handling that is perfect for each unique frame that we build. Custom geometry is included as standard on our 1-Level bikes, giving us the opportunity to build the perfect bike for each rider 100% of the time.
