[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 9.9 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

Shootout: Trek Slash 9.8 v Norco Range C 9.2

Jun 2017

No, this isn’t silly, it’s amazing! And especially available from the big manufacturers, it simply says that riders are pushing the boundaries of mountain biking and the technologies involved have made them a reality. Watch the video here. Take 160mm of travel and jam in a bike with 29″ wheels, and you’ll end up with a …

Trek Slash 9.9 29 RSL (2017) review - MBR

Apr 2017 · Alan Muldoon

The new Trek Slash 29 sounds rock and roll and looks stunning, but does it go like a bat out of hell? When it’s time to go fast it gets the job done.

Highs
  • Great sizing and geometry.

  • Class-leading Fox suspension.

  • Takes Plus-size wheels.

  • Looks drop-dead gorgeous.

Lows
  • Could easily accommodate a 150mm dropper.

  • Stem lengths need to be shorter.

  • Bontrager SE4 tyres are fast rolling with good puncture resistance, but the level of grip doesn’t match the aggressive attitude of the Slash.
