GRAVEL FROM THE GROUND UP Designed from the ground up for gravel use, the Terra is anything but a converted road bike or a slim mountain bike. The Terra is gravel. It brings more comfort to your adventures on the road and finally allows you to discover where that gravel path at the end of the asphalt road leads. Or how about an adventure through the night? Out there, the big wide world awaits you. And the Terra is ready to discover it with you.
