The Pinarello X is a premium endurance road bike designed for riders who want the brand's signature racing aesthetic paired with a more forgiving, upright posture. Introduced alongside the flagship Dogma X, this generation of the X series prioritizes long-distance riding without resorting to mechanical suspension. The defining visual and structural feature is the X-Stays rear triangle, a multi-member seatstay design intended to damp vibration while preserving the lateral stiffness needed for sharp acceleration.
Pinarello also updated the platform to clear modern, high-volume road tires, officially accommodating up to 35mm rubber. While it shares a silhouette and aerodynamic cues with Pinarello's pure race bikes, the X series is built around an endurance-specific geometry that reduces the need for extreme spacer stacks. It suits cyclists who want a fast, responsive road feel but prefer a geometry that accommodates long days in the saddle.

Geometry & fit.
9 sizes published.
Pinarello utilizes its Endurance+ geometry for the X series, creating a fit that is significantly more relaxed than its pure race models. The design features a higher stack and shorter reach, allowing riders to achieve a comfortable, upright posture without relying on excessive headset spacers. This makes the platform highly adaptable for a wide range of flexibility levels.
Handling is tuned to be neutral and stable, striking a balance between high-speed composure and low-speed maneuverability. To ensure this ride character remains consistent across the exceptionally broad nine-size run, Pinarello employs two different fork rakes. This keeps trail figures relatively uniform whether riding the smallest or largest frame, resulting in steering that feels predictable on fast descents and steady on steep climbs. While the frame geometry promotes an endurance fit, riders should note that some builds ship with relatively long stems, which can stretch the effective reach and slightly alter the intended upright posture.

The lineup.
5 builds, ranging $3,250 – $11,000.
The Pinarello X lineup is divided into multiple tiers—X1, X5, X7, and X9—differentiated primarily by carbon fiber grade and component specification. The entry-level X1 utilizes Toray T600 carbon and a mechanical Shimano 105 drivetrain, while the X5 steps up to a lighter T700 carbon frame paired with Shimano 105 Di2. Both of these lower-tier models feature traditional two-piece aluminum and carbon cockpits.
The premium X7 and X9 models share the highest-grade Toray T900 carbon frame, shedding weight while maintaining structural stiffness. The flagship X9 is equipped with top-tier Shimano Dura-Ace Di2, but reviewers point to the X7 as the sweet spot for value. The Shimano Ultegra Di2 version of the X7 delivers nearly identical shifting performance and includes the same premium Most Talon Ultra integrated carbon cockpit found on the top model, offering a significant price reduction without a meaningful drop in ride quality. Across all builds, the frame features an Italian-threaded bottom bracket for straightforward maintenance, though home mechanics should note that certain cockpit and seatpost adjustments require a less common T20 Torx tool.
From the press.
1 review from the cycling press.
Reviewers characterize the Pinarello X as a highly responsive machine that leans heavily toward the performance end of the endurance spectrum. On the road, the frame delivers excellent power transfer and acceleration, but testers note it is noticeably stiffer than many of its direct competitors. The front end, particularly on models equipped with the one-piece carbon cockpit, transmits significant road feedback, with one reviewer noting it "felt buzzier than most endurance and all-road bikes" (Velo). Similarly, the rear triangle and deep aero seatpost prioritize power delivery over plushness, leading to some skepticism about how much vibration the distinctive X-Stays actually absorb.
To access the bike's endurance capabilities, reviewers strongly emphasize maximizing tire volume. The frame's generous clearance is its primary mechanism for comfort. Swapping to high-volume rubber transforms the ride, as testers found that a "swap to a 35 mm tire seemed to change the bike quite a bit" (Velo). Crucially, this added cushioning does not dull the bike's speed, with reports that "ride quality improved dramatically without a noticeable difference in top-end speed" (Velo). Ultimately, the consensus points to a fast, communicative road bike that relies on careful tire selection to smooth out rough pavement, rewarding riders who want a stiff pedaling platform rather than a deeply compliant cruiser.
