Seeking a singletrack and bikepacking hardtail? Timberjack Eagle 70 Transmission is versatile enough to do both. Its aluminum frame is responsive and durable, designed with long, low, and slack geometry that grants confidence steep, techy terrain and preserves pedaling efficiency for riding to backcountry campsites.

Our Alternator dropouts let you adapt to different hub standards and drivetrain setups (including single speed) by swapping dropout plates. Timberjack’s bottle and cargo mounts make it easy to stash all the supplies you need for a long day (or more) of trail riding — no hip pack needed.

The RockShox Psylo Silver RC fork delivers 140mm of trail-calming travel to help keep you in control on technical sections. SRAM’s Eagle 70 Transmission 12-speed groupset offers a wide gear range and trail-ready durability, while the four-piston DB4 brakes can haul you to a stop in a hurry. Whether you set up Timberjack to be your playful trail hardtail, comfortable bikepacking hardtail, or both, it’s up to the task.

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.

Alternator 2.0 UDH-compatible dropouts

The Alternator 2.0 dropout system on this Timberjack comes equipped with SRAM UDH-compatible, fixed-position dropout plates. Other Alternator 2.0 dropout plates (sold separately) allow for single-speed adjustability and accommodate different hub standards.

On-bike cargo

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 downtube, plus top tube mounts for our EXP-R Series Trillium Top Tube Bag means room for more ride essentials. Rear rack capability (with Salsa Rack-Lock seatpost collar) opens 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.
