2021 Timberjack GX Eagle 29

Archived

The all-new Timberjack is proof that hardtails are evolving just as quickly as their full-suspension siblings. We’ve brought a slew of updates to our aggressive trail hardtail that make it a pure joy to ride. The geometry is longer, lower, and slacker with a steeper seat tube for a little extra assurance when you’re rolling down that rock face and clearing that root-covered climb. More cargo mounting options allow you to ride without a pack, or load up and go bikepacking for the weekend. Adjustable Alternator 2.0 dropouts open up possibilities for ride tuning and drivetrain options. The 29 x 2.6” wheel and tire package maintains momentum and traction through the trail’s tricky spots, and SRAM’s GX Eagle group keeps you moving efficiently any time gravity stops working in your favor. The all-new Timberjack: experience hardtail mountain bike evolution.

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.

130 mm Suspension Fork

Soak up the harshness of gnarly roots, rock gardens, drops, or whatever’s in your path with 130 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.

FAQ

What size wheels/tires can I use on this frame?

Timberjack is designed for 27.5 x 2.8" or 29 x 2.1–2.6" wheels and tires

Can I use a suspension fork on this frame?

Yes, this frame is designed and tested for use with a suspension fork with an axle-to-crown length up to 563 mm (typically 150 mm of travel). Check the fork manufacturer's specifications to ensure the model and travel combination you intend to use is equal to or less than this length. Using a longer fork will void the frame warranty and could result in frame failure.

How do I take care of the Alternator 2.0 dropouts?

We recommend periodically removing the bolts and cleaning the dirt and grime off of the hardware and frame surfaces. Then, lightly regrease the threaded parts and re-assemble.

Do you offer touch-up paint?

No, we do not offer touch up paint. Hobby shops or automotive stores are excellent places to find paint. We suggest you test the paint on a scrap piece of metal before using it on your frame.

I crashed and dented (or cracked) my frame. Is it safe to ride?

Stop riding your frame immediately and take it to the nearest Salsa authorized dealer for inspection. A dented or cracked tube represents a structural weakening of the frame, and is a safety risk.
