2026 Salsa Timberjack SLX 29 - Terracotta Orange

With Timberjack, we set out to design the most versatile hardtail mountain bike around. Timberjack SLX 29 starts with an aluminum frame built on progressive trail geometry that's plenty sendy on descents without feeling awkward pedaling back up. The 140 mm RockShox Psylo Silver RC fork handily manages trail chatter for a controlled ride. With ample on-bike storage, you can leave the backpack or hip pack at home. Our Alternator 2.0 dropouts are adjustable to allow for many different drivetrain options and ride characteristics. 29 x 2.5" wheels and tires offer a nice blend of grip and rolling efficiency. Shimano's SLX 1 x 12 drivetrain hits the sweet spot of functionality and affordability.

Features

On-Bike Storage

• Adventures require gear and riders should get to choose whether they carry it on their bike or on their body

Frame Protection

• Our products are built from experience - we've been there enough to know that a carbon fork can benefit from added protection just as much as the downtube on a suspension bike.

Alternator Dropouts

• Adjusts chainstay length to modify ride traits and tire fit (with adjustable swing plates)
• Tensions chain for single-speed use (with adjustable swing plates)
• Gives riders upgrade options

Additional Features

6061-T6 Aluminum Tubing

Timberjack is built from our proprietary, top-shelf 6061-T6 aluminum tubing, which is double- and triple-butted in the main triangle for a light, responsive, and durable frame with great trail feel.

Timberjack Geometry

Our second-generation Timberjack geometry is longer, lower, and slacker for aggressive riding. A 66-degree head tube and long wheelbase make for a stable ride, while a long reach and steep (75-degree) seat tube balance weight distribution for efficient pedaling. Short chainstays (adjustable from 420-437 mm) keep the rear end nimble for responsive handling.

140 mm Suspension Fork

Soak up the harshness of gnarly roots, rock gardens, drops, or whatever's in your path with 140 mm of suspension travel up front. Timberjack accommodates forks with up to 150 mm of travel.

Adjustable TranzX dropper post

Get your saddle out of the way for steep descents and technical sections with the included dropper post. 30 mm of tool-free travel adjustment lets you dial in the right travel for your fit and riding style.

Alternator 2.0 Dropouts

Our adjustable Alternator dropout system lets you run Timberjack geared or single-speed and accommodates multiple hub standards. Built-in adjustability gives you 17 mm of wheelbase travel so you can dial in your preferred ride characteristics.

Bottle & Accessory Mounts

SM-XL frames have two bottle mounts-including a Three-Pack mount on the downtube-in the main triangle (XS frames have only the Three-Pack mount on the downtube). All sizes feature an accessory mount on the underside of the down tube, plus top tube mounts for our EXP Series Direct Mount Top Tube Bag means room for more ride essentials. Rear rack mounts open up possibilities for larger loads.

Full-Length Internal Routing

Full-length internal routing for brake lines and shift cable housing means more reliable performance in sloppy conditions, simplified maintenance, and a better fit for frame bags.

Wheel and Tire Options

Timberjack is compatible with both 27.5 x 2.8" and 29 x 2.1-2.6" wheel and tire combinations.
