The Mosaic
G-Series

The Mosaic G-Series. For every kind of gravel.

This is where it’s at. Whatever gravel means to you, there’s a Mosaic G-Series model ready to exceed your drop-bar multi-surface adventure riding expectations.

From the pinnacle of World Cup proven, go-anywhere, do-anything, compromise-never gravel performance of the big tire GT-1 45 that fits tires as big as 48c’s, to our all-road ripping, fast-gravel GT-1 AR that fits up to 40c, to pushing possibilities into even further with the GT-X models that accommodate mountain bike tire sizes and gearing for uncharted singletrack and up-for-anything adventure.

All models are available as full custom GT-1 level featuring made-to-order, rider specific fit and finish and our lightest, liveliest butted titanium tubing, or the batch-built GT-2 level utilizing straight gauge titanium tubing and standard sizing to the price down If gravel riding is your thing, G-Series is for getting after it, and it’s just a matter of matching the right model to your riding style.
