Gravel
Orbea Terra
2026 · 700c wheels · 6 sizes
The 2026 carbon Terra gravel bike, built around the OMR carbon frame with a 1.5 inch lower headset, 45 mm tyres as stock and plenty of mounts. The same frame and geometry are used across the M20 Team, M20i Team, M21e Team 1X, M31e Team 1X and M35 Team builds. Components listed here are from the M20 Team build. Orbea publishes the effective top tube separately; it is a few millimetres shorter than reach and stack with the 74 degree seat angle would suggest.
