MOSAIC CYCLES

Creative dissatisfaction. That’s the origin of the Mosaic Cycles enterprise, one born from a desire to see a bike transformed into an engine for self-expression, personal achievement and years of amazing miles. Founder Aaron Barcheck imagined as a child, planned as a teen and then gained competence from active apprenticeship in his twenties. 

Elevating his skills to the level of Master Builder at a frame maker,

Aaron diligently prepared to make his vision relevant to a new generation of riders.  Not coincidentally, there’s a value story embedded in this journey to excellence. 

Mosaic can make you a bespoke bike frame in either steel or titanium. Catering for a variety of disciplines with each one thoroughly thought out to deliver the right ride for what you want.

MOSAIC GT-1

On the spectrum of gravel bikes, the GT-1 is closer to a road bike than an adventure bike. The geometry lands between traditional road and off-road frame specs with short chainstay length, steep front head angle, oversized head tube, and carbon fork. This provides a snappy feel on the road with low bottom brackets, a slightly longer wheelbase, and tire size make for stable off-road handling. It is built on a flat mount disc brake platform for all-terrain stopping force and also creates clearance for a 38c tire. The 3/2.5 double butted tubeset can take the abuse of riding all year in any climate without worry of corrosion or denting with minimal care. Smaller diameter tubes are hand selected according to rider weight, providing a more compliant ride. In contrast to the oversized and responsive X or R-Series tube selection that can be oriented towards race performance, the GT-1 aims at a different category of performance: one of comfort, longevity, and functionality. Optional fender and rack mounts make the GT-1 a perfect bike for year round riding.
