More and more trail bikes are trying to become mini enduro bikes, but the Santa Cruz Tallboy takes a different approach. With a low system weight, plenty of pop and a clear focus on fun, it follows its own philosophy. Can the Tallboy hold its own against the competition, and does its 13.34 kg weight deliver the performance it promises?

Longer, slacker and more capable: Many modern trail bikes are now moving dangerously close to enduro territory. With 140/130 mm of travel (f/r), the Santa Cruz Tallboy deliberately takes a different approach. Rather than chasing enduro levels of travel like some of its competitors, the Tallboy focuses on low weight, maximum efficiency and a playful ride character, the core principles of a true trail bike.

First introduced in May 2026, our Tallboy X0 AXS RSV in size L tips the scales at just 13.34 kg, which makes it the lightest bike in the entire test field. Priced at € 9,499, it features the second highest spec in the range, surpassed only by a limited edition model equipped with a RockShox Flight Attendant suspension system. But is the Tallboy the playful alternative to increasingly capable trail bikes, or has Santa Cruz taken this approach too far?

Spec and Features of the Santa Cruz Tallboy X0 AXS RSV

With its CC carbon frame, the Tallboy, like the new Nomad, uses the highest grade and lightest carbon layup in Santa Cruz’s range. The new four bar suspension frame is claimed to be a full 300 g lighter than its predecessor with the traditional VPP rear suspension. The understated paint finish, subtle branding and clean lines give the Tallboy a refined appearance. However, the proportions don’t completely convince us. The large front triangle looks slightly oversized compared with the compact rear end, while the substantial swingarm inspires confidence from a technical perspective but appears somewhat bulky visually.

In the finer details, Santa Cruz again show the benefit of their years of experience. The chainstay protector is among the best in this group test, running a long way down the stay. Together with the robust down tube protector, the bolted shuttle guard and the small fender at the Horst Link pivot, it leaves the frame thoroughly shielded against rock strikes and shuttle runs on pickup trucks. Santa Cruz also fit a OneUp chain guide as standard. Another standout: the 210 mm OneUp V3 dropper on our size L test bike inserts fully into the frame, making excellent use of the available seat tube length.

The storage compartment in the downtube also leaves a premium impression. The cover closes securely, the rubberised locking tabs prevent rattling, and the two supplied zippered bags make it easier to organise your tools and essentials while reinforcing the bike’s high quality feel. Even a OneUp 100 cc pump fits comfortably inside the Tallboy’s storage compartment. The only minor criticism is the appearance, as the storage cover looks slightly added on and doesn’t blend into the frame quite as seamlessly as solutions from brands such as Yeti or Trek.

The Tallboy’s cable routing is less convincing, though. While the cables disappear into the frame directly behind the head tube and remain impressively quiet internally, the sections around the cockpit are comparatively long and tend to rattle on the trail.

The spec of the Tallboy X0 AXS RSV is in line with Santa Cruz’s usual high standards. Up front, it features a RockShox Pike Ultimate fork with the Charger 3.1 damper, while a RockShox Deluxe Ultimate shock handles suspension duties at the rear.

Braking is handled by the new SRAM Motive Silver paired with 200/180 mm rotors front and rear. For a lightweight trail bike, this combination works well, helped by the SRAM HS2 rotors. Shifting is taken care of entirely by the SRAM X0 Eagle AXS Transmission, including the X0 series cassette and chain, which impresses with precise gear changes and excellent durability.

Fender or Spoiler?
The small, high mounted mudguard behind the head tube is also finished to a very high standard.

The Race Face Turbine SL stem features a flip function, allowing riders to switch from a +6 mm rise to a -6 mm drop position for a more XC focused setup. It is paired with a size specific OneUp carbon handlebar, measuring 800 mm wide on our size L test bike. For the wheelset, Santa Cruz rely on their in house Reserve 30 SL carbon wheels with DT Swiss 350 DEG DF hubs. The DEG freehub system uses a low engagement angle for direct power transfer, while the DF technology allows riders to adjust the defined dead spot to 0°, 10° or 20°. This helps reduce pedal kickback and lets you fine tune the ride feel to suit both the bike and your riding style.

Aufgezogen sind vorne wie hinten The bike rolls on MAXXIS Forekaster tires front and rear, featuring the MaxxTerra compound and EXO casing. This combination works well for moderate trails. For more demanding alpine riding, however, we’d recommend at least upgrading to an EXO+ casing at the rear and fitting a more aggressive front tire, such as the DISSECTOR, for additional grip.

Tuning tip: Fit a more robust casing at the rear and, if needed, switch to a more aggressive front tire with the softer MaxxGrip compound.

The Geometry of the Santa Cruz Tallboy X0 AXS RSV

With 472 mm reach in size L, the Santa Cruz Tallboy sits almost exactly in the middle of our test field. Its 1,239 mm wheelbase is also relatively compact, sitting slightly below the average. Combined with 438.5 mm chainstays, the geometry creates a balanced setup on paper, designed neither for maximum stability at high speed nor for extreme playfulness.

The head angle can be adjusted between 65.1° and 64.8° via the flip chip. We rode the bike in the slacker setting, which gives the Tallboy slightly more confidence and capability on descents. At the same time, the effective seat tube angle of 77.2° feels suitably modern and places the rider in a centred position above the bottom bracket. With a 635 mm stack, the front end is neither particularly tall nor low, creating a well balanced riding position.

Light, direct and incredibly playful, the Tallboy makes even familiar home trails feel exciting again.

The Santa Cruz Tallboy X0 AXS RSV on the trail?

Santa Cruz provide a detailed setup guide on their website with all the key suspension and cockpit settings. However, we weren’t convinced by the recommended air pressures. While the guide suggests 174 psi in the shock for our test rider, the Tallboy felt noticeably more balanced and controlled with just 159 psi.

How does the Santa Cruz Tallboy X0 AXS RSV climb?

Climbing is where the Santa Cruz Tallboy shows its greatest strengths. The compact riding position and pleasantly low front end place plenty of weight over the front wheel, and combined with the Tallboy’s low overall weight, make it the strongest analogue climber in this group test. Despite the sporty riding position, the Santa Cruz is comfortable even on longer ascents.

Lightweight, a strong climber and guaranteed to put a smile on your face, the Tallboy shows its strengths on the climbs.

The rear suspension remains relatively active under pedalling and, in the open mode, bobs slightly more than some competitors. However, that movement translates into excellent traction on technical climbs. For longer fire road climbs, the RockShox Deluxe Ultimate shock can be almost fully locked out, creating a noticeably firmer and more efficient rear end.

Surprisingly, on particularly technical climbs, we expected slightly more from the Tallboy’s geometry and traction focused rear suspension. At times, it lacked that final level of confidence, although much of this can be attributed to the tire choice. Either way, the overall impression remains clear: no other analogue bike in this group test climbs as strongly and effortlessly as the Santa Cruz Tallboy.

How does the Santa Cruz Tallboy X0 AXS RSV perform on descents?

After just the first few corners, it becomes clear why the Tallboy tops our agility ranking in this group test. No other bike is quite as effortless when it comes to spontaneously switching lines. The low system weight, the balanced handling and suspension’s impressive pop make it the most playful bike in the entire test field. Manuals, quick direction changes and boosting off trail features all come naturally and require very little effort. The Tallboy encourages you to use every change in terrain and actively generate speed from the trail itself.

The low weight and supportive rear suspension encourage you to actively use every roller and trail feature to generate speed.

Despite its lively character, the Santa Cruz delivers a well balanced ride feel. You’re integrated centrally into the frame and feel comfortable from the very first metres of trail. The handling is incredibly intuitive, making it easy to build confidence quickly, even on unfamiliar trails. The fast rolling MAXXIS Forekaster tires also contribute to the playful character, helping maintain speed and efficiency, although the front tire reaches its grip limit slightly earlier in demanding corners than more aggressive alternatives.

The suspension perfectly matches the Tallboy’s character. The RockShox Pike Ultimate and Deluxe Ultimate work together seamlessly, delivering a sensitive response and plenty of support through the mid stroke. At the same time, the rear suspension makes excellent use of its available travel, effectively converting it into traction. Despite its relatively short travel, the suspension handles hard impacts without harsh bottom outs and offers surprisingly impressive reserves.

Of course, the Tallboy’s concept comes with certain limitations. In fast, technical high speed sections and long braking bumps, it reaches its limits earlier than the longer travel bikes in this group test and ranks last when it comes to outright composure. This impression is reinforced by the higher noise levels, with the cables in front of the head tube creating more rattle on rough trails than we’d expect from Santa Cruz.

The SRAM Motive Silver suits the lightweight trail bike concept well. Its braking performance is surprisingly strong when paired with the HS2 rotors and is more than sufficient for this type of riding. On long and steep descents, however, it requires a slightly more vigilant riding style compared with the more powerful brake systems in this group test.

Santa Cruz show plenty of attention to detail with the Tallboy. The storage compartment, frame protection and premium spec all impress, with only the cable routing taking some of the shine off an otherwise strong package.

Who is the Santa Cruz Tallboy X0 AXS RSV for?

The Santa Cruz Tallboy X0 AXS RSV is aimed at riders looking for an exceptionally lively and playful trail bike. Thanks to its low weight, class leading agility and excellent climbing performance, it excels on flowing trails as well as long days in the saddle. If you like to actively ride the terrain, use every roller to generate speed and enjoy climbing just as much as descending, the Tallboy is one of the most entertaining companions in this group test.

Our conclusions about the Santa Cruz Tallboy X0 AXS RSV

The Santa Cruz Tallboy X0 AXS RSV proves that maximum riding fun doesn’t demand huge amounts of travel. No other bike in this group test combines such agility with such strong climbing and such intuitive handling. The firm, traction-focused suspension delivers far more than its 140/130 mm travel figures suggest. There are drawbacks: the relatively high noise levels, the lightweight stock tire setup and the limited composure when the terrain turns seriously rough. But for riders who understand the Tallboy’s character and aren’t after a mini enduro bike, it offers one of the most enjoyable, versatile trail experiences in the whole test.
