Gravel Capability With the Heart and Soul of a Road Bike

Why We Love It
With the world of Gravel growing more and more competitive each year, it's a welcomed sight to see Colnago throw their take on a gravel taming race rig in the mix. There seems to be two distinctive directions gravel bike designs go: adventure or race. As we mentioned, and to no surprise, Colnago chose to lean on their strengths and put together a gravel steed optimized around a 40mm tire, a slight geometry tweak to cater to gravel demands, but at its core, the heart and soul of a performance road bike.
