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.

Trek made some changes for Gen 6 of the Slash. Cooper has had a good amount of time to suss them out.

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

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.
Incredible composure on the rowdiest terrain
Plush & well-controlled suspension
Surprisingly efficient pedalling performance
Mullet setup injects welcome agility
Loads of in-built adjustability
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 has brought pedalling efficiency to the high-pivot market, but lost some of the design’s renowned sensitivity in the process
Well-mannered pedalling for a 170mm high-pivot bike
Balances stability and agile handling
Silent
Full of useful features
Firm shock damping tune reduces suspension sensitivity
Stiff wheels and handlebars
Tyres hinder capability

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.
Excellent geometry and balanced ride
Composed, capable, and predictable suspension
Climbs well for such a downhill-focused bike
Excels in challenging terrain
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

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.
