ORBEA RALLON Downhill Frameset 2027 - Over Engineered To Go Fast.
The new Rallon Downhill Frameset is a full-suspension downhill mountain bike born from 185 years of Orbea's racing heritage. This isn't just a bike; it's the exact same machine ridden by Orbea's pro racers on World Cup tracks, proving its elite performance. With its downhill-tuned design, uncompromising suspension, and low centre of gravity, it's engineered to make you faster and more confident on the gnarliest trails.
The Rallon Downhill Frameset offers unmatched adjustability, letting you fine-tune your ride for any track or style thanks to its innovative Attitude Adjust system. Built to endure, its robust construction and robust, capable components ensure it's a reliable partner for aggressive riding. Get ready to elevate your riding experience.

THE ULTIMATE DOWNHILL MACHINE
The Orbea Rallon Downhill Frameset is built for pure speed. With 170mm of rear travel paired with 180mm front travel, this MTB is ready for the rough stuff. Its suspension kinematics are designed to be as active as possible, reacting smoothly to even the smallest bumps, which is essential for maximum grip, control and absorption on rough trails at high speeds. Riders can also fine-tune the suspension and change the progressivity by around 5%, from 22.5% to 27.5% to suit any track.
Orbea's GravityLink suspension system strategically positions the shock low in the frame, creating an exceptionally low centre of gravity. This enhances stability and agility, especially when leaning into corners or catching air. For ultimate customisation, riders can add up to 395g of internal weights to the bottom bracket for increased composure, or remove them for quicker reactions. The Rallon Downhill Frameset features refined geometry, perfected through years of testing. Precise carbon lay-up ensures balanced front and rear triangle stiffness, delivering exceptional grip and confidence on rough terrain.

ADJUSTABILITY FOR EVERY TRACK
Attitude Adjust
From full-throttle downhill runs to chilled-out laps with friends, every ride is different—and Rallon is built to match. Its versatile adjustability gives you the perfect Downhill setup, no matter where the day takes you.
On the Trail: Dial in Your Ride
Quick adjustments let you fine-tune your Rallon for every track and trail:
- Shock Progressivity: Use the GravityLink flip chip to adjust shock progression by ~5%, from approximately 22.5% to 27.5%, giving you more control over your suspension feel.
- Head Angle Adjust: Change the head angle by 0.75º using the offset headset cup—tweak your geometry to match the terrain.
- Weighted Bottom Bracket: Boost stability by adding weight low on the frame. Rallon includes 93 g, 95 g, and 395 g weights that mount to threaded holes in the GravityLink.
Off the Trail: Custom Fit for Your Style
Your riding style is personal—and your Rallon should reflect that. During the purchasing process, Orbea gives you meaningful options to make it yours:
- Chainstay Length Options: Choose 442 mm chainstays for a nimble, playful ride or 450 mm for maximum stability at speed. Orbea’s testing shows preference for chainstay length depends more on riding style than frame size—so they let you decide.

BUILT FOR ABUSE
- Fully Guided Internal Cables: Cables are completely guided through the frame, eliminating rattle and making maintenance simple and hassle-free.
- Upgraded Chainstay Protector: A soft rubber guard with hollow recesses absorbs chain slap more effectively, keeping noise down and your ride smoother.
Signature Orbea Features
True to Orbea’s mountain bike DNA, Rallon includes thoughtful, rider-focused touches:
- FLP Multitool: Integrated into the frame for quick trailside adjustments.
- LOCKR Storage: Hidden, spacious in-frame storage for tools or essentials.
- Sealed Bearings: Shields bearings from the elements.
- Second Skin Protection: Factory-applied vinyl guards preserve your frame’s finish from scuffs and trail wear.
