Each AR-Zero is built to order for a single rider — not a size run, not a stock geometry, but a frame conceived, engineered, and hand-built around one person. It's less a bicycle model than a singular object, made once, made right, made for you.

Born from the Zero Ops program, the AR-Zero is the all-road counterpart to the RT-Zero — built for riders who want the same uncompromising, one-off construction with room to explore beyond pavement. Fitting up to a 40mm tire with a road groupset, the AR-Zero carries every hallmark of the Zero platform: an in-house designed carbon seatmast and topper, CNC-machined proprietary components including our IS52 head tube, and one-piece dropouts engineered and manufactured entirely under one roof.

With the AR-Zero this is where Mosaic's craft is most exposed. Every tube is mitered, fit, and welded by hand, hours of painstaking work compressed into joints that will carry a rider for decades. Once the frame is built, it moves to our finish department, where the same standard holds — each frame prepped, painted, and finished by hand, with the same patience and attention given to every weld. There's no shortcut to a frame like this — no template to pull from, no process to rush. It's built the way an artist approaches a canvas: with patience, intent, and total commitment to getting it right. The result isn't just a bike. It's a piece of work that will outlast trends, outlast components, outlast the moment it was built — a frame made to be ridden for a lifetime, and passed down as something more than transportation.

Geometry

Rider Specific Geometry

As with all of Mosaic’s made to order frames, the AR-Zero is designed fit-first design approach for every individual rider. 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 with the RT-Zero, giving us the opportunity to build the perfect bike for each rider 100% of the time.
