GT-1 X is designed for maximum all-terrain capability. Go further. And then keep going.

As the most versatile gravel bike models in the G-Series, GT-1x redefines adventure cycling by adding room for mountain bike gearing and tire widths up to 29x2.25. Designed to challenge the limits of what a gravel bike can do and blur the line between aggressive gravel and mountain biking, X models are available with SRAM UDH and feature geometry optimized for loaded handling and all-around capability. If you aim to ride across Alaska (we did) or simply want a gravel rig that can handle pretty much anything, the GT-X is your move.

The GT-1x is built with lighter, double-butted titanium tubing in tube diameters and wall thicknesses designed to handle loaded riding and rough surfaces while saving some precious weight. Available with custom sizing, finish and rider’s choice of back, rack and bottle mounts, each GT-1x is handmade for riders who demand no-compromise performance and versatility when exploring the wild and untamed.

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.

Your Bike. Your Fit.

Mosaic Batch Built Geometry

The Mosaic Batch Built program utilizes our proven size run of geometry to deliver a simpler, more standardized offering, available in a shorter timeframe. By building standard geometry frames together in a batch, configured in an intentional and similar way, we’re able to deliver a batch-built frame in 2-3 weeks, while allowing the customer to choose how their bike is finished.

Finishes: Choose your wow factor.

The finish is the first thing we see. And when you’re excited by the sheer look of your Mosaic, it also gets you excited to get out and ride. And that’s what it’s all about. So whether you choose to let the metal be the star of your titanium frame, or opt for a super colorful paint scheme that’s uniquely you, the goal is to come up with a look that’s going to light you up and get you out there. Ready? Let’s make it yours.
