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

Trek Slash 9.9 X01: first ride review - MBR

Sep 2020 · Alan Muldoon

First ride review of 2021 Trek Slash 9.9. Trek’s 29in enduro trail blazer returns with more travel and a progressive makeover.

Highs
  • Fast and easy to ride. Revised geometry and sizing bring it bang up-to-date. Suspension set-up is straightforward and the drain port in the bottom of the down tube should stop the water pooling below the shock.

Lows
  • All of the cables need shortening to stop them rattling. Trek’s MinoLink is a non-feature as we never clipped a pedal even in the low setting.

Mar 2018

Like it or not punks, big wheeling is what’s hot right now! We have been lucky enough to have our hands on a number of new pushys, including a brand-new 2018 Trek Slash 9.7 for review. With a huge season within the world of downhill and Enduro both domestically and internationally, you cannot deny 29’ inch wheels are making their mark on disciplines of MTB that years ago we would’ve thought may have stayed committed to the traditional 26’ inch […]

2018 Trek Slash 9.8

Mar 2018 · Bturman jeff.brines

The Slash set the new benchmark for long-travel 29ers not long ago, and 2018's version attempts to meet the same standard. This one is stiff, light, and an excellent option for long adventures.
