The GT-1 is Mosaic’s top of the line gravel road bike, hand-built right here in Boulder, CO. Its 3/2.5 double-butted titanium frame is built to take the punishment of any road or season, remaining corrosion and dent free throughout its lifetime with minimal care. The main tubing is smaller in diameter than what is used in Mosaic’s road frames to provide extra compliance and comfort over rough terrain, while its oversized bottom bracket and headtube keep it stiff at key points to help deliver the watts to the ground when it counts. In the expansive spectrum of gravel bikes, Mosaic’s GT-1 skews toward the racier end. It is similar in geometry to a road bike than an adventure rig. It’s steep angles and short chainstays keep the bike snappy, giving it the lively road manners one expects from a fast road bike. However, the addition of a lower bottom bracket, a slightly longer wheelbase, hydraulic disc brakes, and clearance for much larger tires, gives it stability and capability off-road that no road bike can match. It truly is a do-it-all bike that can perform in road races, fast group rides, and endurance off-road events like the Dirty Kanza and the Belgian Waffle Ride. Any situation where there may be mixed terrain between asphalt, dirt, and gravel is where the GT-1 will shine. It is built up with Shimano’s high-end electronic Dura-Ace Di2 drivetrain, which will ensure perfect crisp shifts in all conditions. The GT-1 is a bike ready for any serious rider looking to race the road less traveled.
