TREK SLASH GEN 6 REVIEW - A GENERATIONALLY DEFINED TWO-WHEELED ENDURO MARVEL - Mountain Bike Action Magazine

May 2024 · Nelson

Our feelings about the Gen 6 Slash may be mixed, but the good outweighs the bad, and we were able to get past the inconveniences.

The New Trek Slash 9.9 Plows As Expected, But Pedals and Pops Too!

Jan 2024 · Steve Fisher

Trek gives the 2024 Slash a high-pivot linkage with 170mm travel and mixed wheels, making a capable and well-rounded long-travel bike.

2024 Trek Slash Review | Is this high pivot enduro bike fashionably late, or just late to the party?

Jan 2024

The 2024 Trek Slash looks nothing like the old one. So how do all the changes play out on the trail? Read on for our Trek Slash review.

Highs
  • Incredible composure on the rowdiest terrain

  • Plush & well-controlled suspension

  • Surprisingly efficient pedalling performance

  • Mullet setup injects welcome agility

  • Loads of in-built adjustability

Lows
  • Extra pulleys add complexity & noise

  • Tyres too flimsy for the application

  • Downtube storage is on the small side

  • Chainstay armour lacks damping

  • GX derailleur clutch failure

Trek Slash 9.9 X0 AXS T-Type review

Nov 2023 · Luke Marshall

Trek has brought pedalling efficiency to the high-pivot market, but lost some of the design’s renowned sensitivity in the process

Highs
  • Well-mannered pedalling for a 170mm high-pivot bike

  • Balances stability and agile handling

  • Silent

  • Full of useful features

Lows
  • Firm shock damping tune reduces suspension sensitivity

  • Stiff wheels and handlebars

  • Tyres hinder capability

Field Test Review: 2024 Trek Slash - Rides Like a Session

Oct 2023 · Dario DiGiulio

Trek did a very good job making the Slash a quiet bike, then seemingly lost the plot when they specced a hard rubber chainslap protector that does little to mitigate the drivetrain noise in bumpy terrain.

Highs
  • Excellent geometry and balanced ride

  • Composed, capable, and predictable suspension

  • Climbs well for such a downhill-focused bike

  • Excels in challenging terrain

Lows
  • Chassis may be too stiff for some

  • Chain drop issues due to improperly spaced lower idler (fixed)

  • Stock chainstay protector did very little to manage noise

Bike Review | Trek Slash Gen 6

Sep 2023

The all-new Trek Slash is beefed up in celebration of its sixth iteration. This fresh design features an oversized, 19-tooth idler pulley and a high-pivot rear suspension configuration for the first time in the model’s lineage. Travel has been increased to 170 millimeters, pushing it further into the all-out, winch-and-plummet ethos that so many enduro bikes seem to be gravitating to. Our 9.9 version was spec’d with Bontrager’s RSL integrated handlebar and stem, a SRAM T-Type XO drivetrain, and the all-new RockShox Vivid Ultimate rear shock. The previous Slash was an impressive bike. It was impressively light for an enduro bike and was surprisingly efficient to pedal around all day. The new Slash Gen 6 leans more heavily toward the chairlift and shuttle culture side of the mountain bike world with some extra heft and additional pulleys in the drivetrain. However, with the oversized pulley and lighter casing tires, I found the Slash to climb the most efficiently of any high-pivot bike I’ve reviewed thus far. I attribute this mostly to the large, 19-tooth upper idler.

Trek’s brand new enduro bike, the Slash 2024, relies on a high pivot suspension design and mullet wheel setup. We spent 6 weeks putting the new Slash through its paces.

Highs
  • Integrated, confidence inspiring riding position

  • Combines excellent composure and agility

  • Potent suspension provides plenty of pop and reserves

  • Practical features like the integrated storage compartment and mini-tool

Lows
  • Spec has some blemishes

  • Idler pulley grinds lightly when pedalling uphill
