Rally geometry positions the rider forward and low, favoring an efficient climbing stance while maintaining the balance necessary for confident descending. The chassis includes adjustable geometry at three points: a three-position head tube that allows angle changes, a two-position bottom bracket height adjustment, and chainstay flip chips that alter wheelbase and weight distribution. The 65-degree head angle represents the middle setting, with options to slacken or steepen depending on terrain preferences. Bottom bracket height sits at 339mm in the low position, keeping the center of gravity planted without sacrificing pedal clearance. Combined, these adjustments let riders tune the Levo R's handling character across a wide range without suspension modifications.

The FOX 36 SL Factory fork handles front suspension through a GRIP X damper with high-speed compression, low-speed compression, and low-speed rebound adjustment. The 44mm offset contributes to the responsive steering feel that defines the Rally platform. At the rear, the FOX FLOAT Factory GENIE shock brings Specialized's patent-pending air spring technology to the Rally chassis with a dedicated tune. GENIE delivers a flat, coil-like spring curve through the initial 70 percent of travel, maintaining consistent traction and support through the bump zone where most trail riding occurs. The final 30 percent transitions to a progressive ramp that resists bottom-out without the harsh end-stroke spike that characterizes traditional air springs. Two-position compression adjustment allows riders to firm up the shock for climbing efficiency or open it for descending confidence.

Power delivery from the S-Works 3.1 motor reflects Specialized's focus on natural-feeling amplification. CoreCoat winding encapsulation enhances heat dissipation while reducing operational noise. Larger full-metal gears with HardDrive surface treatment ensure consistent engagement throughout extended climbs. The motor mechanism decouples from the driveside housing to minimize structure-borne vibrations—a refinement that becomes apparent on sustained efforts where motor drone would otherwise accumulate into fatigue. Adaptive current injection responds to cadence and speed changes in real time, providing smooth support through technical low-speed sections while fading naturally as velocity approaches the assistance limit.

The 840Wh integrated battery provides up to 4.4 hours of riding in efficiency-focused modes. Side-entry battery access simplifies service and swaps—a single hex key removes the hatch, no motor extraction required. The modular system accepts an aftermarket 600Wh battery for lighter weight on shorter missions or a 280Wh range extender for multi-hour adventures. All batteries meet IP67 water and dust resistance standards. The included 12-amp smart charger reaches 80 percent capacity in under an hour and offers four charge modes: Standard, Fast, Eco, and the 80-percent limit that maximizes long-term battery health.

SRAM's XX Eagle AXS Transmission handles shifting through a 10-52t cassette that provides range for everything from steep fire road climbs to high-speed descents. The T-Type architecture eliminates the external derailleur hanger, mounting the mechanism directly to the frame's UDH interface for improved alignment and crash resistance. SRAM Motive Ultimate brakes deliver stopping power through 4-piston calipers and 200mm rotors front and rear. The AXS POD Ultimate controller integrates shift and dropper actuation into a single interface.

Roval Traverse SL II carbon wheels pair hookless rims with 30mm inner width to Industry Nine Hydra 2 hubs, which engage through 690 points of contact for near-instantaneous power transfer. DT Swiss Revolite spokes connect hub to rim. Specialized Purgatory tires in 29x2.4 provide traction at both ends—GRID casing up front, GRID Trail casing at the rear for additional sidewall protection. The Roval Control SL RISE integrated cockpit eliminates the stem-bar junction, treating the entire front end as a unified carbon structure with 50mm reach and 780mm width.

The MasterMind TCU provides system control through a 2.2-inch high-resolution display that integrates with the Specialized App for detailed customization. MicroTune adjusts motor support in 10-percent increments, while Smart Control manages battery consumption automatically. Apple Find My integration and Turbo System Lock add security layers. Over-the-air updates refine firmware without dealer visits. SWAT internal storage in the downtube holds trailside essentials above the battery, and a steerer-tube multitool provides access to common fasteners.
