Since its introduction, the Tallboy LT has been changing commonly held notions regarding the correct usage of 29er wheels. Specifically, the LT has proven time and time again that the larger wheels are perfect for flying through aggressive terrain with aplomb, and the Santa Cruz Tallboy LT X01 AM complete mountain bike rounds the LT out with a build kit that's undeniably up to the task. With FOX suspension, a Rockshox Reverb Stealth dropper post, and hand built wheels, you'll have plenty of reason to feel confident on the scariest terrain. SRAM's new X01 drivetrain employs a ultra-wide range cassette and a 1x11 format to shed the weight and complexity of front derailleurs, without sacrificing the gear range found in a traditional double. Basically, the LT is exactly what you need, whether you're looking for an enduro rocket or an all-day trail tamer.

The focus of the LT necessitates aggressive geometry and confidence inspiring construction, hence the oversized hydroformed tubing for supreme stiffness and unrivaled confidence. The oversized tapered head tube enables the use of stiffer tapered forks, and provides a solid junction for the oversized, hydroformed down tube and top tube. The top tube and down tube have a subtle bow to them, which dissipates impacts to greatly improve the strength of the frame. The oversized tubing in the rear triangle makes for a flex free ride that's especially important given the added leverage imparted by larger wheels. That stiffness is only aided by the 142x12mm rear thru axle. Anyone who's ridden the LT will tell you that the feel is balanced, yet decidedly aggressive. Accordingly, it receives stealth routing for dropper seatposts, for more control on descents and technical sections. The result is a frame that's light enough for endurance racing, and strong enough for anything you can throw at it.

At the heart of the LT's handling is a highly refined VPP suspension. It's a suspension platform that's widely beloved for its blend of pedaling efficiency and trail-erasing smoothness. VPP employs two aluminum counter-rotating links to achieve this balance. If you're wondering how it works, the upper link provides most of the rotation as the bike compresses into the sag point. This yields a vertical wheel path, which you'll notice in the form of a firm feel during acceleration. As the bike compresses deeper into the suspension, the lower link activates, moving the axle path rearward. The rearward axle path enables the rear wheel to travel out of the way of impacts, so the ride is smooth, not jarring. And you'll find the same collet-style pivot hardware that has become standard for Santa Cruz's suspension bikes. That means that your pivots stay tight and are simple to service, even for home mechanics.

Construction is key, but the geometry of the LT is an integral part of its near-magical handling. The 69.5 degree head angle doesn’t look particularly slack on paper, but with the larger wheels and longer-travel fork, it inspires incredible confidence at speed, while remaining maneuverable when you need it. With the travel-adjustable TALAS fork, you have the option of dropping the fork and steepening the head angle by roughly a degree, which aids the climbing control. Roomy top tubes per size enable the use of a modern cockpit setup consisting of a shorter stem and wider handlebars. The seat angle is fairly steep at 72.6 degrees, for an aggressive climbing position that enables efficient power transfer. At 17.7 inches, the chainstays are long enough for incredible climbing traction and confidence inspiring stability, without being long enough to compromise the quickness of handling. The short of stature will notice that the smallest size that the LT comes in is a medium. That's due to the increased standover height associated with the longer-travel platform and larger wheels. While that will keep some riders off of the LT, we can't help but admire Santa Cruz's approach that they'd rather not build smaller 29'ers if they're not confident in the handling.

As the name implies, the X01 AM build features SRAM's 11-speed X01 groupset. By using a massive 10-42 cassette, you're able to get a gearing range that's similar to a traditional double chainring drivetrain, and you save the weight and complexity of a front shifter and derailleur. The concept has been proven at the highest levels of competition via SRAM's XX1 groupset, so the reliability and functionality leave nothing to be desired. Suspension duties are handled by FOX units front and back, in the form of a 34 TALAS fork, and a FLOAT CTD evolution rear shock. The fork employs FOX's FIT sealed damper for consistent performance on long descents, and the none-more-gold Kashima coating, in addition to travel adjust. The TALAS spring allows you to lower the fork to 110mm of travel for more responsive climbing, and lengthen it to the full 150mm of travel for descending. Speaking of which, Shimano's venerable XT brakes handle stopping duties. You'll find an Easton Havoc alloy handlebar and Truvativ AKA stem handling the steering, and the staff favorite Rockshox Reverb Stealth dropper post puts control of your saddle height at your fingertips. Rounding out the build kit is a hand built wheelset comprised of DT's legendary 350 hubs laced with DT spokes to WTB i23 tubeless compatible rims. They're wrapped in Maxxis High Roller II tires, which have developed a loyal following for their fast rolling and incredible grip across a broad range of trail conditions.

The Santa Cruz Tallboy X01 AM complete mountain bike is available in three sizes from Medium to X-Large, and in the colors Yellow/black/silver, and Black/red/silver.
