GRAVEL FROM THE GROUND UP From the very first moment, the Terra is designed specifically for gravel use and is far from being a converted road bike or a slim mountain bike. The Terra is all about gravel. It provides you with more comfort on your road adventures and allows you to finally discover where that gravel path at the end of the paved road leads. Or how about an adventure through the night? Out there, the vast world is waiting for you. And the Terra is ready to explore it with you.
