Just a stone’s throw from The Pro’s Closet headquarters, Mosaic Bicycles are hand-made in Boulder, Colorado, with the goal of embracing the lifestyles we all live through their builds. Mosaic builds their frames in only steel or titanium due to the superior ride quality and recyclability they both offer. 

Mosaic offers custom builds for riders looking to get the most out of their bike or stock sizing if customization is not your thing. Each custom frame will take about a month to make and will leave the shop with the highest level of precision and detail. 

The customization of Mosaic’s framesets does not end there, however. Once the frames geometry is finalized, you can choose from a wide array of custom paint finishes by Spectrum Paint to make your ride stand out from the rest.

The GT-1 is Mosaic’s answer to a high-performance gravel bike. They describe it as being closer to a road bike than an adventure bike, and for a good reason. The GT-1 has short chainstays, a steep head tube angle, and a carbon fork to provide a quick and responsive feel on the road. Its low bottom bracket, long wheelbase, and larger tires give the GT-1 enough stability to venture off the beaten path.

When Mosaic set out to build the ultimate cyclocross bike, they took notes from Colorado’s front range courses to reflect what the best cyclocross bike would need to do. The result is a titanium frame paired with an ENVE carbon fork, front and rear 12mm thru-axles, and disc brakes that all work together to create the ultimate race machine.

Be it racing CX on Sunday or riding for days in the backcountry, the lightweight titanium frame will carry you and your gear wherever the adventure leads.
