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 while 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.
