The Trek Top Fuel has been significantly updated for 2025, though the visual changes are subtle. Maintaining a similar silhouette to its predecessor, the fourth-generation Top Fuel features a completely redesigned frame with leaner tubing for weight reduction. More importantly, these changes enhance compliance and tracking on rough terrain, improving the bike’s performance as an xc bike.
A key innovation is the unique 4-position Mino Link at the lower shock mount. This allows riders to fine-tune both geometry and rear suspension leverage rate. By simply changing the shock stroke, the rear travel can be adjusted to either 120mm or 130mm. Combined with its compatibility with 120-140mm travel forks, the latest Top Fuel is undeniably the most adaptable version yet, solidifying its place as a top xc bike.
Having initially tested the Top Fuel 9.8 GX AXS in its factory setup, I found it to be an outstanding all-around xc bike. Subsequently, by extending both the fork and shock, fitting more aggressive tires, and swapping a few components, it transformed into a remarkably capable 140/130mm travel trail bike.
More recently, I explored the opposite end of the spectrum, configuring the Top Fuel as a 120/120mm travel xc bike. It performed convincingly in this configuration, particularly with the RockShox SID fork and adjustments to the rear shock setup. While serious racers might overlook it due to the frame’s 2.6kg weight, lack of remote lockout routing, and single bottle capacity, the Top Fuel offers exceptional handling and technical capability for a 120mm travel xc bike.

The Specialized Epic has been a dominant force in xc bike racing since its debut in 2002. Famously built around the Brain shock, the Epic was known for its hardtail-like pedaling efficiency, achieved through its automated system. However, the Brain system added weight and complexity and could be harsh over rough terrain, a trade-off in the pursuit of xc bike performance.
For 2024, the Epic has undergone its most significant transformation. Specialized has completely abandoned the Brain system and increased suspension travel to 120mm both front and rear. Paired with progressive XC geometry and an adjustable Hi/Lo flip chip, the Epic 8 offers significantly improved plushness and descending capability compared to its predecessors, marking a new era for this xc bike.
Despite the increased travel, it remains quick on climbs thanks to its lightweight frame and sophisticated 3-position suspension system. Featuring custom internals from RockShox, the SID fork and SIDLuxe shock provide open, lock, and a Magic Middle setting that delivers a firm yet responsive pedaling platform. This makes it a versatile xc bike for various riding conditions.
Most Epic models feature a TwistLoc remote to control the three suspension modes, but the flagship S-Works model utilizes the advanced RockShox Flight Attendant system for automatic adjustments. While it comes with a very high price tag, it represents the pinnacle of XC suspension technology in an xc bike.
The Epic 8 is packed with features like SWAT downtube storage, a hidden steering limiter, and guided internal cable routing. For an in-depth look, refer to our comprehensive Specialized Epic 8 review.

The Canyon Lux Trail, initially launched in 2021, served as a longer travel variant of the Lux race bike. To manage costs, both models shared a rear end, with the Lux Trail featuring a unique, slacker, and longer front triangle. Paired with a 120mm fork and a more trail-oriented build kit, it was a cost-effective way to expand the lineup, though not without its drawbacks as a dedicated xc bike.
Addressing previous criticisms, Canyon completely revamped the Lux Trail for 2024. The new carbon frame Lux Trail now features a 120mm fork and 115mm of rear travel and is Canyon’s first mountain bike with internal storage. The storage hatch is well-designed, and the optional top tube-mounted multi-tool is a thoughtful addition, enhancing its practicality as an xc bike.
Practicality extends to the threaded BB and tool-free thru-axles, but cable routing is less refined. Control lines routed through the headset create a messy cockpit. Considering the Lux Trail’s efficiency, ditching the remote lockout could have resulted in a cleaner setup and improved dropper post lever ergonomics, aligning better with xc bike preferences.
Despite these minor issues, the Lux Trail is a strong performer. While heavier than the Lux World Cup, it remains agile on twisty singletrack. The smoother suspension and longer stroke dropper post enhance descending capability, making it fun on technical terrain, broadening its appeal beyond pure xc bike racing. See our detailed Canyon Lux Trail review.

- Lows: Not the firmest under power, proprietary fork and PF30 BB may deter some, no dropper post on complete bikes, some limitations in xc bike versatility.
The Cannondale Scalpel, the oldest bike in our list, debuted in early 2020. Representing the 8th generation of Cannondale’s flagship full suspension race bike, the Scalpel uses a novel chainstay design with a solid leaf-spring section forward of the dropouts. This allows suspension to behave like a four-bar linkage, with less weight and improved lateral stiffness, an innovative approach to xc bike design.
On trails, the Scalpel is impressively smooth for a 100mm travel XC race bike, offering excellent traction and uninterrupted pedaling over rough terrain. It’s also progressive with good big-hit support, though like the Merida Ninety-Six, the sensitive rear suspension might feel slightly soft. This can be adjusted by reducing sag or using the dual lockout for sprinting, adjustments suitable for an xc bike.
Long-distance riders will appreciate dual bottle mounts, and the integrated STASH tool system is excellent. Less appealing are the PF30 bottom bracket and proprietary A.I. drivetrain offset, potential drawbacks for some xc bike enthusiasts.
The Lefty Ocho fork is polarizing, but its long 55mm rake results in quick steering, while needle-bearing internals and a triangular slider make it exceptionally stiff and sensitive. The difference was clear in back-to-back testing against a conventional Fox fork, highlighting the unique performance of this xc bike. Get full details in our Cannondale Scalpel review.
