If you have been watching the enduro race circuit closely, you already know Orbea has been quietly building something ambitious. The Orbea Rallon 2026 geometry represents one of the most configurable gravity platforms ever released: a single carbon frame that transforms between a 170mm enduro race bike and a 200mm downhill machine through Orbea’s new GravityLink suspension system. For riders who want one frame that genuinely covers both disciplines, the numbers tell a compelling story.

What Makes the Orbea Rallon 2026 Geometry Unique
The Rallon is not just another long travel enduro bike with a marketing angle. Orbea engineered the frame around a modular GravityLink rocker system that physically changes the suspension kinematics, progression rate, and travel depending on which link you bolt in. The enduro configuration runs 170mm rear and 180mm front travel. The DH configuration pushes that to 200mm rear and 203mm front. Same frame, same carbon layup, completely different suspension behavior.
What sets this apart from flip chip adjustments on other bikes is the scope of transformation. The GravityLink sits underneath a bolt-on downtube guard, with the shock positioned so low it actually pierces the downtube. That through-downtube shock mounting drops the center of gravity significantly, and every reviewer who has ridden the Rallon comments on how planted it feels at speed.
Size-Specific Carbon Layups
Orbea adjusts the carbon fiber stiffness of the front triangle using different layups tailored to each frame size. A size Small gets a different flex profile than an XL, compensating for differences in rider weight and leverage. This is not a new concept (Santa Cruz does something similar), but Orbea applies it across all four sizes with their OMR carbon construction.

The enduro configuration uses a 180mm fork (Fox Float 38, 44mm offset) paired with 170mm of rear travel through a Fox Float X shock. Here are the numbers in the neutral headset position with 450mm chainstays:
| Measurement | S | M | L | XL |
|---|---|---|---|---|

Switch to the DH GravityLink and the Rallon becomes a different animal. The fork grows to a 203mm Fox Float 40 dual crown, rear travel jumps to 200mm through a Fox Float X2, and the geometry shifts accordingly:
| Measurement | S | M | L | XL |
|---|---|---|---|---|
| Reach (mm) | 425.2 | 450.2 | 473.3 | 500.3 |
| Stack (mm) | 632.5 | 641.6 | 650.7 | 659.8 |

| Standover (mm) | 767.6 | 760.6 | 762.5 | 767.5 |
The DH GravityLink gets its own flip chip with two progression options: 25% (linear) and 30% (progressive). Three bolt-on ballast weights ship with every DH setup: two side weights (93g and 95g) and a central weight (395g) that mounts to the GravityLink itself. Total added mass: 583 grams of tuneable bottom bracket weight for high-speed stability.
Ride Characteristics: What the Numbers Mean on Trail
The Enduro Setup
A 64.25 degree head angle in 2026 is moderate for the enduro category. The Specialized Enduro 2026 runs 63.5 degrees, and the Santa Cruz Megatower 2026 sits at 63.5 degrees as well. Orbea is not chasing the slackest angle here. Instead, they are betting on the low center of gravity and 170mm of well-tuned travel to provide stability without sacrificing steering precision.
The 478mm reach on a Large puts the Rallon Enduro right in the middle of the current enduro field. Combined with a steep 79.1 degree seat angle, the climbing position stays efficient despite the gravity orientation. The short 442mm chainstay option makes the rear end snappy for technical switchbacks, while the 450mm option adds stability for open, fast terrain.
That 28mm BB drop is worth noting. It places the bottom bracket lower than most enduro bikes (the Transition Patrol runs closer to 25mm), which contributes to the Rallon’s trademark planted feel. Reviewers consistently describe the ride as “glued to the ground” with enormous traction through rough sections.
The DH Setup
Drop to 63.8 degrees in DH mode and the Rallon sits right between the Santa Cruz Nomad 2026 and a dedicated race DH bike. The mullet wheel configuration (29″ front, 27.5″ rear) is mandatory in DH mode, giving riders the rolling speed of a big front wheel with the rotational agility of a smaller rear.
The DH chainstay shortens to 439.9mm across all sizes, which is remarkably compact for a 200mm travel bike. For context, the Specialized Demo 11 2026 runs 440mm chainstays. Orbea clearly prioritized agility over high-speed wheelbase stability, which aligns with the modern World Cup trend of shorter, more manoeuvrable DH bikes.
GravityLink Suspension: The Engineering Details
The GravityLink uses a four-bar linkage with what Orbea calls a Concentric Boost pivot, rotating around the rear axle. Orbea positioned the pivots to minimize pedal kickback: the DH setup produces under three degrees of total pedal kickback across the entire travel range. Anti-rise starts at just under 65% before trailing off to about 57%, and anti-squat sits low (just over 50% at top-out, dropping to nearly 0% by end of travel in a 34-16 gear).
These kinematic choices make the suspension extremely active and supple. The trade-off is less pedaling efficiency compared to bikes with higher anti-squat values. For an enduro race bike that spends most of its timed stages going downhill, Orbea clearly chose descending performance over climbing efficiency.
The enduro GravityLink offers Fox Float X Live Valve Neo compatibility for electronic compression damping, automatically adjusting between climbing and descending modes. The DH version runs fully mechanical components optimized for reliability under race loads.
Adjustability Deep Dive: Headset, Chainstays, and Progression
The Rallon offers more geometry adjustability than almost any bike on the market:
Headset cups: Three positions providing +/- 0.75 degrees of head angle adjustment. Combined with the GravityLink flip chip, the enduro version spans from roughly 63.5 to 65.5 degrees of head angle range.
Chainstay length: Two rear triangle options (442mm and 450mm) selected at time of purchase. Unlike a flip chip you toggle in the garage, this is a build-time choice.
GravityLink progression: Both the enduro and DH links offer two progression settings via flip chip (22.5%/27.5% enduro, 25%/30% DH).
Ballast weights: 583 grams of bolt-on weight for the DH setup, positioned at the GravityLink to lower the center of gravity further.
Standover: One of the lowest standovers in the enduro category. Orbea claims most riders can fit a 240mm dropper post regardless of frame size, thanks to the “Steep ‘n’ Deep” frame design.
Size Recommendations and Tall Rider Fit
With 25mm reach increments between sizes and only four sizes available (S through XL), the Rallon follows the modern trend of fewer, more widely spaced sizes. Here is how the sizing breaks down by rider height:
- Small: 155 to 168cm (5’1″ to 5’6″)
- Medium: 168 to 178cm (5’6″ to 5’10”)
- Large: 178 to 188cm (5’10” to 6’2″)
- XL: 188 to 198cm (6’2″ to 6’6″)
For tall riders (6’2″ and above), the XL offers a generous 505mm reach in the enduro configuration, paired with 656.2mm of stack. That is competitive with the tallest sizing options from Trek and Specialized, though riders over 6’4″ may want to verify standover clearance and consider the 450mm chainstay for proportional wheelbase balance.
The steep seat angles (78.8 degrees on the XL) ensure that even the largest size maintains an efficient pedaling position. Taller riders often struggle with seat angle on long travel bikes because the effective angle flattens as the saddle rises; Orbea’s actual seat angles are steep enough to compensate.
Where It Sits in the Market
The Rallon occupies a unique position. No other brand offers a single frame that genuinely converts between enduro and DH racing configurations. Canyon’s Torque can be adjusted with flip chips, and the Trek Fuel EX Gen 7 offers modular travel, but neither approaches the Rallon’s transformation range.
Pricing starts at $5,699 for the Enduro E-Team build and $8,299 for the DH D-LTD. That is a significant investment, but consider that you are effectively getting two bikes in one frame. A comparable standalone enduro bike plus a DH bike would cost substantially more.
The frame uses Orbea’s OMR carbon for both front and rear triangles with an alloy rocker link. Internal LOCKR frame storage in the downtube adds practical trail-side carrying capacity, and internal cable routing keeps noise to a minimum.
FAQ
Can you switch the Orbea Rallon between enduro and DH configurations at home?
Yes, the GravityLink swap is designed to be done with basic tools. You will also need to swap the fork (from a single crown 180mm to a dual crown 203mm) and the rear shock (from a Float X to a Float X2 with longer stroke). The chainstay length choice (442mm or 450mm) is made at purchase and cannot be changed without a new rear triangle.
What wheel sizes does the 2026 Orbea Rallon support?
The enduro configuration supports full 29 inch wheels or a mullet setup (29 inch front, 27.5 inch rear). The DH configuration runs mullet wheels only. Different GravityLink versions accommodate each wheel configuration.
How does the Orbea Rallon compare to the Santa Cruz Megatower for enduro racing?
The Megatower runs a slacker 63.5 degree head angle compared to the Rallon’s 64.25 degrees, and offers 165mm of rear travel versus 170mm. The Rallon’s lower bottom bracket (28mm drop vs. roughly 22mm on the Megatower) gives it more planted traction, while its adjustable progression rates let riders tune suspension feel. The Megatower is simpler with fewer adjustments, while the Rallon rewards riders who want to tinker.
Is the Orbea Rallon good for tall riders over 6 feet?
The XL frame offers 505mm of reach and 656.2mm of stack, which is competitive with most enduro bikes in this size range. The extremely low standover height and compatibility with 240mm dropper posts on most sizes make it particularly accommodating for tall riders. Riders over 6’4″ should verify standover clearance and consider the 450mm chainstay option for balanced proportions.
What is the weight of the 2026 Orbea Rallon frame?
Orbea has not published an official frame weight for the 2026 Rallon. The OMR carbon frame with alloy rocker link is competitive with other high-end enduro frames. The DH configuration adds up to 583 grams of optional bolt-on ballast weights for stability tuning.
The Bottom Line
The Orbea Rallon 2026 is not trying to be the slackest, the longest, or the lightest enduro bike on the market. Instead, it is trying to be the most versatile gravity platform, and the geometry backs that claim. A frame that genuinely converts between 170mm enduro racing and 200mm downhill with proper kinematics for each configuration is unprecedented.
If you race enduro and occasionally enter DH events (or simply want one frame that handles everything from bike park laps to stage racing), the Rallon makes a strong case. Start by deciding which chainstay length suits your riding style, pick your GravityLink configuration, and adjust the headset cups to dial in the head angle. The Rallon gives you the tools to build exactly the gravity bike you need.
