Description

This ready-to-ride Mosaic GT-1 is a purpose-built gravel machine, stripped of excess and built with intent. Shorter chainstays, mechanical shifting, and 650b wheels give the bike a nimble, confidence-inspiring ride that feels as timeless as it looks. Finished in turquoise and dressed in a full Bjorn kit – cockpit, saddle, seatpost, and bottle cages – the build is completed with Rene Herse Juniper Ridge TC tires. Equal parts aesthetics and function, nothing here is accidental.

Simplicity guided every choice. Fulcrum Rapid Red 650 wheels, Campagnolo's Ekar groupset, and Bjorn components deliver reliability without batteries or complexity. While the industry continues to chase larger wheels, the 650b platform remains unmatched for maneuverability, cornering confidence, and versatility across mixed terrain.

Frame size is approximately a 54.
