[R]eviewed: Trek Slash 9.7

Mar 2018 · March 16, 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.

Trek Slash 9.8 Review

Feb 2018 · Christoph Bayer

The biggest innovation on the Trek Slash is hidden inconspicuously inside the shock. Trek calls it Thru Shaft, and it’s the latest addition to Trek’s suspension technology. Although the technology is not entirely new, it has never been properly implemented on a mountain bike. For an overview of the test fleet head to the group […]

Trek Slash 9.9 29 Race Shop Limited review

Aug 2017 · Josh Patterson

Phenomenally stiff, impeccably controlled, hyper-fast enduro racer that’ll Slash your previous times. Buy if you want maximum speed and accuracy on the roughest, fastest trails

Highs
  • Superbly shaped, jaw-droppingly stiff full-carbon frameset

  • Ultra-sensitive, maximum grip but HD communicative and immaculately poised Fox suspension

  • Mostly excellent wheel, tyre and component pack

Lows
  • TALAS fork adds cost and drag

  • 125mm Bontrager dropper is short and slow
