2021 Timberjack Single Speed 27.5+

Archived

Gears? You don’t need gears. Keep it simple with the all-new Timberjack 27.5+ Single Speed. Timberjack’s updated trail hardtail geometry makes steep descents and technical challenges a bit more manageable without eliminating pedaling and climbing ability. It’s a versatile machine, too—just in case your rides go beyond wildly enjoyable singletrack sessions. The frame offers many mounts for carrying extra ride supplies for all-day rides or overnighters. The adjustable Alternator 2.0 dropouts ensure that you can always add gears later on if you want. The 27.5 x 2.8” wheel and tire combo makes this single speed mountain bike a nimble performer or even a low-maintenance bushwhacking machine if your rides are heavy on bandit trails and deer paths. The redesigned Timberjack 27.5+ Single Speed is your playful new ride partner.

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.
