Orbea Gravel Terra M31e Team 1X – Custom 2025

Endless explorations, extended getaways, country roads, and forest trails—everyone has their unique definition of gravel. But what’s undeniable is that a gravel bike must tackle all these with mastery, speed, and comfort... and most importantly, with maximum fun. Designed from the ground up for gravel, the Orbea Terra M31e TEAM 1X is not an adapted road bike or a downsized MTB. The Terra IS A TRUE GRAVEL BIKE. Add comfort to your road rides, finally discover where that forest trail leads, or let your adventures extend into the next day. The world is vast, and the Terra is ready to explore it by your side.

Fast and lightweight, the Terra M is the most performance-oriented version in the range, perfect for conquering country roads and forest trails.
