The Beta Tests: Trek Slash 9.8

Mar 2021 · Lydia Tanner

The Trek Slash has been 29-inch-only since 2016, and the 2021 version is evidence of its head start in the big-wheel enduro category.

Highs
  • Superb high-speed stability

  • Great traction in variable terrain

  • Supple and generous-feeling suspension

Lows
  • Less maneuverable at slow speeds

  • A lot of bike to get back up the hill

Field Test: 2021 Trek Slash - Ready to Race

Dec 2020 · Mike Kazimer

The Slash received multiple updates for 2021, but it's still an enduro race machine at heart.

Highs
  • Light and stiff frame – encourages you to go fast

  • Great shock tune

  • In-frame storage

  • Wide range of available frame size options

Lows
  • Seat tube angle could still be a bit steeper

  • Shorter cranks and an even longer dropper post would have been nice to see

Bike Review | 2021 Trek Slash 9.9 X01

Oct 2020 · Spencer Johnson

The venerable Trek Slash is back for 2021, armed with more suspension travel than ever before. The new Trek Slash 9.9 X01 comes equipped with the ever-capable, 170-millimeter RockShox ZEB Ultimate fork and a custom, 160-millimeter RockShox Super Deluxe Ultimate shock, placing it squarely in the hard-charging enduro category. For me, one of the most welcome updates for the new Slash is the seat angle, which has been steepened to 75.6 degrees, putting the rider’s weight directly between the wheels—and making for a much more comfortable seated position while climbing. The relatively long reach of 486 millimeters, together with the mid-length chainstay of 437 millimeters, creates a bike that stays firmly planted while you sweat your way to the top of a mountain. But the most impressive feature of the new Slash is its impressively light weight—something I wouldn’t automatically expect from a bike in the longer-travel range, especially one with 29-inch wheels. The lightweight frame construction and ultra-light build of the 9.9 X01 version I tested was noticeable from the moment I started huffing up my first climb.

First Ride: 2021 Trek Slash 9.9

Sep 2020

Trek was an outlier with the previous Slash when they went all-in on enduro 29. Things have changed, but the Slash stays true to its mission: Slashing.
