Rallon DH

The 2026 Orbea Rallon DH marks the brand’s first dedicated downhill platform available to the public. Built around a carbon OMR frame, it is a purpose-built gravity machine designed for steep, high-speed tracks and World Cup-level racing. The chassis relies on a downhill-specific GravityLink lower shock mount to deliver 200mm of travel front and rear, rolling exclusively on a mixed 29-inch front and 27.5-inch rear wheel setup.

What sets the Rallon DH apart is its deep adjustability. Riders can tune the bike's center of mass using bolt-on bottom bracket weights, while a flip-chip alters suspension progressivity. Headset cups offer angle adjustments, and buyers select their preferred chainstay length at the time of purchase. It is a highly tunable, uncompromising race bike aimed at riders who prioritize outright traction and stability on the most demanding descents.

Fit and geometry

The Rallon DH geometry is defined by an exceptionally low standover height and a deep, centered rider position. This frame architecture allows for maximum freedom of movement over the bike, keeping the rider's weight low between the mixed wheels. The head tube angle sits at a slack 63.8 degrees in the neutral setting, but an offset headset cup allows for a steeper or slacker adjustment to suit specific track gradients.

Handling characteristics are heavily influenced by the chainstay length, which must be selected when ordering the bike. The longer 450mm option provides a balanced, race-focused stance for high-speed stability, while the 442mm rear end injects a degree of agility into tight corners. The concentric Boost 12x148 rear pivot isolates braking forces, keeping the suspension active and the geometry consistent when decelerating hard into steep chutes. Overall, the posture is aggressive and forward-leaning, designed to keep weight driving through the front tire on severe descents.

Builds

The Rallon DH lineup is concise, offering two distinct tiers built around the identical carbon OMR frame. The flagship D-Ltd build is a race-ready package equipped with top-tier Fox Factory suspension, featuring a Grip X2 damper in the fork and a custom-tuned Float X2 Factory shock. It relies on a proven Shimano Saint drivetrain and powerful four-piston Shimano XTR brakes paired with large rotors for sustained stopping power. This build rolls on Orbea’s in-house Oquo Mountain Control alloy wheels wrapped in heavy-duty Maxxis downhill tires.

For riders looking to supply their own components or build a custom race bike, the Standard option serves as a frame-and-shock starting point. It includes the same Fox Float X2 Factory shock and GravityLink hardware but omits the fork, drivetrain, brakes, and wheels. Both options include integrated frame features rarely seen on dedicated downhill bikes, such as fully guided internal routing, a quiet chainstay protector, downtube storage, and a magnetic multitool hidden in the main pivot.

Reviews

Reviewers characterize the Rallon DH as a deeply planted, high-speed specialist that prioritizes grip over playfulness. The suspension kinematics and low center of gravity work together to keep the chassis glued to the ground, with testers noting that the bike "sticks to the trail like an industrial hoover to a carpet" (Enduro MTB). This extreme traction allows riders to hold lines through off-camber roots and heavy rock gardens without deflection. The rear suspension is highly sensitive off the top, as the shock "breaks into the travel without hesitation" (Pinkbike), erasing small chatter and isolating the rider from harsh impacts.

The addition of modular weights to the GravityLink was widely praised for calming the bike through rattling, high-frequency impacts. Testers found that the extra mass mimics the stability of a heavy e-bike, reducing fatigue on long runs. Once pointed down a steep grade, the bike "effortlessly builds and maintains speed" (Bikeboard), carrying momentum through technical sections where stiffer frames might hang up.

The primary tradeoff for this ground-hugging nature is a lack of agility on flatter terrain. The linear suspension design absorbs jump lips rather than boosting off them, meaning the bike requires more rider effort to get airborne. It is a specialized tool that "craves intensity, speed, and gradient" (Enduro MTB), rewarding aggressive riding on steep tracks while feeling sluggish on mellow flow trails.
