TREK Roscoe 9

Availability: Out of stock

Roscoe 9 is our best all-mountain alloy hardtail, built for lap after lap of grin-inducing fun. A 140mm FOX Rhythm 36 fork, powerful 4-piston brakes, and a fast-and-grippy wheel and tire combo deliver awesome capability whether you're nailing jumps or picking through gnarly rock gardens.

It's right for you if...

You love the serious fun and connected feel a hardtail brings to the trail, and you want one that’s spec’d with top-notch parts that love rough and tumble runs as much as you do.

The tech you get

A lightweight aluminum frame, a 140mm FOX Rhythm fork with beefy 36mm stanchions, a Shimano SLX/XT 1x12 drivetrain with a wide range of gears for climbing, powerful 4-piston brakes, and a dropper post for room to move around on the bike on descents, corners, and jumps. Plus, fast-rolling 29er wheels and wide, grippy 2.6" tires.

The final word

Rip laps, catch air, and crush techy descents on our best hardtail. Of all the rad parts on this bike, the FOX Rhythm 36 fork is the best upgrade—it’s capable of soaking up even the roughest lines.


The Walkthrough

favorite_borderWhy you'll love it

  1. 29er wheels and wide 2.6" tires make for a grippy, confident, and fast-rolling ride
  2. Bigger, stiffer 36mm fork stanchions won't flex, so you can push harder with more precise, confident steering that helps you stay on your line
  3. The FOX fork's air spring can easily be adjusted for a specific rider weight, and it's lighter than a coil spring
  4. The dropper post lets you lower your saddle on the fly so it's out of the way on descents
