MOSAIC GT2 45 GRX Limited Complete Build
Description
The GT-2 45 is available now as a complete bike built in Mosaic Batch Built geometry and finished with Shimano's GRX Limited groupset. Frames can be finished to order within the Mosaic Finishwork Program and the complete bike shipped to a Mosaic Dealer for assembly within 1-2 weeks of purchase. Like every Mosaic, the GT-2 45 is built by our team of exceptionally skilled craftspeople here in Boulder, CO every step of the way, from design to frame building, welding, and finishing. The GT-2 45 is designed around a 45mm tire and a gravel groupset, making it ideally suited for gravel rambles way off the beaten path. Shimano's GRX Limited Groupset has a special edition finish that embraces the beauty of metal, perfectly complimenting the aesthetics of a Mosaic frame.
