Mosaic has added two new frameset models to their G-Series lineup of gravel and adventure bikes. The GT-1X and GT-2X are two new Mosaic framesets for riders seeking a big tire, off-road capable titanium adventure bike. Both GT-X frames are designed around a 29×2.25 tire, a gravel-specific or MTB drivetrain, and a geometry that incorporates a longer top tube and shorter stem, allowing the rider to set up their GT-X in a drop bar or flat bar configuration. The addition of optional frame bag and accessory mounts, as well as rack and fender mounts, make the GT-X capable of all-season, all-terrain exploration.

The GT-1X utilizes Mosaic’s top-of-the-line, double-butted titanium tubeset. Custom geometry and a rider-specific tubeset are included as “standard” options on GT-1X, making it a truly custom build. The GT-1X is offered in the rider’s choice of Mosaic Paint Layout or the Mosaic Factory Finish.

The GT-2X utilizes Mosaic’s simpler straight gauge titanium tubeset. The GT-2X is offered in 7 stock sizes from S-XXL, with custom geometry available as an upgrade. The GT-2X is finished in Mosaic’s standard raw finish, with available upgrade options to a Mosaic Paint Layout or the Mosaic Factory Finish.

Every GT-X adventure bike is built to order and finished in Mosaic’s Boulder, Colorado facility. Orders can be placed through a Mosaic dealer, and frames carry a 12 week lead time from the date that the details are confirmed, the order is signed off and put into the build queue.
