2026 Orbea Terra Race M20 LTD - The Mechanical Racer’s Terra
The Terra Race M20 LTD is the purist’s fast gravel machine — lightweight, efficient and built around the refined simplicity of the new mechanical GRX 12-speed drivetrain. If you want the responsiveness of Orbea’s OMX frame without the need for batteries in your shifters, this is the Terra that stays sharp, dependable and race-ready in all conditions.
OMX Carbon Frame – Lightweight & Race-Tuned
Orbea’s top-level OMX carbon delivers stiffness under power and smooth compliance over rough gravel. The vibration-damping rear triangle keeps the bike planted when the pace is high, and 45c tyre clearance keeps it versatile for all-surface racing.
Focused Cockpit Control
The OC GR10 carbon bar provides controlled flex and ergonomic shaping for long race days, matched to the OC RP10 stem for precise steering and immediate response.
Aero Wheels & Fast Tyres
Oquo RP50 LTD carbon wheels offer aero efficiency and quick acceleration, paired with Vittoria Terreno T30 700×40c tyres for predictable grip and fast rolling on hardpack and mixed surfaces.
12-Speed GRX – Refined Mechanical Precision
Shimano’s latest GRX RX820 drivetrain brings crisp mechanical shifting and a wide-range 48/31t × 11–34t gear setup for mixed gradients, race pacing and steep climbs.
Controlled, Consistent Braking
Shimano RX820 brakes provide powerful, modulated stopping through rough descents and loose gravel.
The Verdict
A lightweight, clean-running gravel race bike with premium wheels and the reliability of mechanical GRX — ideal for racers who value responsiveness and simplicity.

Lightest, Strongest, OMX Carbon
Speed starts with OMX: our lightest, stiffest carbon layup. By using fewer pieces and taking more time on each frame to reduce overlap, we are able to save 300 g without losing rigidity.
OC SH-RA10 Aero Cockpit
An exceptionally light and aerodynamic integrated cockpit, with fully internal routing, ergonomic tops, and sprint-ready stiffness - all engineered for speed.
Vibration Damping Rear Triangle
Shaped for speed on rough ground, the rear triangle smooths out vibrations and keeps the rear wheel planted for maximum traction when the pace gets punchy.
Just Right Tyre Clearance
Tyre clearance up to 45C gives you the freedom to run wider, faster-rolling setups — perfect for racing over rough terrain without sacrificing speed.
Size-Tuned Stiffness
Our size-tuned stiffness ensures every frame feels equally responsive and efficient.
