Trek Slash C Gen 6 Frameset (2027)

1/2

The ride, not just the specs

Point it downhill.

Slash is built for big descents, rough terrain, and enduro days. It's long, stable, and calm when the trail gets wild.

If you climb for the best way down, this is the one.

What makes it special

Thoughtful details. Big possibilities.

01
High-pivot suspension
Slash's high main pivot allows the axle to move rearward as the suspension compresses, so the back wheel moves with the force from bumps and gets out of the way faster. On the trail, it feels ultra-smooth while maintaining more momentum with insane traction.
02
Curb the kickback
Slash's oversized upper idler not only eliminates the pedal kickback caused by high pivot, but its size and position also give you just the right amount of anti-squat for efficient pedaling. The lower idler takes chain tension off the derailleur so you get smoother shifting and suspension performance.
03
Mixed wheel size
You get a 29" front wheel for monster truckin' over stuff, with a smaller 27.5" wheel out back for getting rowdy. Want full 29er speed? Just swap the lower shock mount (sold separately) to lower BB height for running a faster wheel out back.

Slash-ready accessories Dial your Slash for slaying the trail with pedals, bottles, and so much more, with our collection of Slash-compatible accessories.
Ride your way Slash has plenty of room for long droppers, big coil shocks, meaty tires, and up to 190mm of front suspension. Plus, there's a place for accessory mounts under the top tube for when your storage door is already full of snacks.
Knock Block Knock Block has your frame's back when things go wrong. It prevents your handlebars from spinning all the way around in a crash, so your hoses won't get yanked, and your controls won't hit the top tube.
Oversized 34.9mm dropper post Bigger is better. The oversized seat tube diameter gives more support and strength for longer travel droppers, and allows for more robust, durable internals that work faster.
Threaded bottom bracket Slash is built for the hardest riding in the harshest conditions with a threaded bottom bracket that's more robust than press fit.

“Pinkbike's 2023 Mountain Bike of the Year”

“Upping the game”
The Slash and the new Vivid shock are a true power couple and required almost zero tuning to get me to a happy spot [...] props to Trek on nailing a great tune for most riders [...] Trek Slash ranks very high on my list of bikes ridden in the last two years. If climbing takes a back seat to downhill capabilities – fun, charging hard and going big – you may not want to wait until we’ve logged enough miles for our long-term review to pull the trigger.

“4.5/5 Stars”
This is without doubt the most efficient high-pivot idler bike I’ve pedalled. While the travel is plush, there’s good support so you can pop and pump down the trail, with a lively and light ride character, while still remaining stable and composed when the trails get rough. Trek has shown what's possible here and it's impressive

“More ‘dynamic edge’ than ever before”
So there are a lot of little things on this Slash that combine really well to produce extra sparkle on the trail. First off, let me just say the suspension performance is simply sensational. The shock requires very little force to move and it changes direction quickly – it feels as buttery as a coil shock. I’d even say the small bump performance is better than any air shock I’ve ridden. Diving into the deeper end of the travel it feels like there is more than 160mm available.
