Timberjack Deore 12 29
Timberjack Deore 12 29
Timberjack Deore 12 can be multiple bikes. Its aluminum frame, trail geometry, and 140mm-RockShox Recon Silver RL all push you to push your limits and get playful on the trail. The multiple bottle and cargo mounts plus the versatility of our Alternator dropout system invite you to explore just how far you can take your Timberjack. Bikepacking? You bet. Single-speeding? Sure.
Shimano’s Deore 12-speed drivetrain and four-piston brakes keep you confidently in control of the pace, whether picking your way up a steep, techy climb or bombing down a flowy line. We think this all adds up to make Timberjack the best hardtail mountain bike for riders who like a little of everything.

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.
