Mosaic GT-1 i55
OUR MOST CAPABLE GRAVEL BIKE YET, READY TO RACE
Years of experience designing, fabricating, riding, and racing bikes in every condition imaginable have led us to the GT-1 i55. In that pursuit, we ended up with a bike made for one purpose: to serve the modern gravel rider and racer.
At the heart of the GT-1 i55 is Mosaic's time-tested, double-butted titanium tube set and proven geometry foundation, delivering confident handling, responsive performance, and durability, year after year.
What sets this model apart is 55mm of tire clearance. To achieve this modern spec, Mosaic undertook a full redesign of the frame: a 3D-printed chainstay yoke for shorter chainstay length, 55mm tire clearance, and clearance for a 50-tooth chainring; an offset seat tube to accommodate the larger tire; and a proprietary Mosaic-designed carbon gravel fork with appropriate gravel offset and a suspension-corrected axle-to-crown.
Put it all together, and there's nothing the GT-1 i55 can't do.
