Summary
The Trek Slash is a highly capable enduro bike, praised for its superb high-speed stability, supple suspension, and excellent traction in variable terrain. It offers a floaty, invincible ride quality with cloud-like landings, making it a favorite for rough and technical trails. While it excels in descending, some reviews note it can be less maneuverable at slow speeds and a bit heavy on climbs.
Superb high-speed stability
Supple and generous-feeling suspension
Great traction in variable terrain
Floaty, invincible ride quality
Cloud-like landings
Less maneuverable at slow speeds
A lot of bike to get back up the hill
Lockout a bit harsh and the open mode too mealy on climbs
It’s the sort of bike that seems to turn the volume down on practically every kind of feature, which of course makes you search for ways to turn the volume back up again.
The new Slash felt almost as though it was hovering above the trail.
The result is a seriously accurate, phenomenally controlled, track or trail dominating high-velocity weapon that’s still pedal efficient and loaded with practical details for big days out.

The Slash 8 strikes the perfect balance between a fun and lively feel, and ultimate chaos-calming composure
Easy to ride, very natural feeling geometry
Great kit for the cash
Easy to throw about yet still calm and stable when it needs to be
Seriously impressive suspension
Tyres aren’t the best in damp mud

The Trek Slash has been 29-inch-only since 2016, and the 2021 version is evidence of its head start in the big-wheel enduro category.
Superb high-speed stability
Great traction in variable terrain
Supple and generous-feeling suspension
Less maneuverable at slow speeds
A lot of bike to get back up the hill

Riding a bike like the Slash over the winter on the North Shore is a rough test scenario, but Trek's newest long travel trail bike has proven up to the task...

Awesome aggro geometry
Precision accuracy
High control cockpit
Internal storage
Efficient pedaling
