Mosaic GT-1

Builds starting from $7700

Custom, handbuilt frames were the original "gravel" bikes - machines built around bigger tire clearance, but with road-going geometry. The Mosaic GT-1 (Gravel Titanium) is a natural evolution of those originals. Keep Reading

Description

The GT-1 is a true standout from the field with custom front triangle butting, internal brake routing, a myriad of finish options, and ENVE's relatively new GRD carbon fork. The GRD is revelatory for the GT-1, giving a much lower ride height versus a comparable cyclocross fork. The result is a front end that's easy to get on top of for technical road descending and quicker handling. Built around 12mm thru-axles, the GT-1 is as stiff as it is flexible, and the indefatigable titanium construction defies both the elements and mishaps. The GT-1 is based on Mosaic’s road-going RT-1, using the same rider-specific custom-butted titanium top and downtubes, and smaller diameter S-bend seatstays for comfort during marathon events like the Belgian Waffle Ride and Dirty Kanza.

Winter bike? Gravel racer? Bikepacking? With Mosaic, the possibilities are indeed endless, with a litany of frame options, from fender/rack mounts, pump pegs, and bespoke paintwork. Internal brake/shift routing is standard, and a 44mm oversized headtube makes room for the GRD's tapered steerer. All of Mosaic's raw ti finish options are available at no charge, and custom paint is also an option. Every Mosaic GT-1 that leaves Above Category is custom-built for the individual, with geometry and tubeset choice based on your answers to our questions about your riding style, current bike setup, riding/racing aspirations, and biomechanical dimensions.

AC Advice

Stiff but not harsh, agile, and ready to take on the rigors of the Unbound Gravel 200, this bike is my go-to when the terrain gets rough! A tried and true platform that is as capable as it is beautiful, especially when paired with one of Mosaic's incredible in-house paint jobs!
