Trek Slash 9.8 XT Gen 5
Slash 9.8 is a carbon enduro mountain bike built to handle big hits, rail corners and rip down the mountain faster than you ever thought possible. Ultra stiff and ultra tough carbon frame, carbon wheels and the most refined suspension tech from RockShox make this long-travel 29er a worthy contender for any dedicated rider and enduro podium.
It's right for you if...
You're looking to tackle huge days on huge mountains, whether it's an enduro race or an epic adventure. You want the light weight and muted vibes of a carbon frame, and you prioritise tunable suspension performance over a shiny top-shelf drivetrain.
The tech you get
A full OCLV Mountain Carbon frame with 160 mm of travel and an all-new RockShox Super Deluxe Ultimate shock with an updated Thru Shaft damper, plus an all-new RockShox ZEB fork with extra-beefy 38 mm stanchions. A Shimano XT 12-speed drivetrain for super-smooth shifting that's easy on the thumb, 4-piston brakes for confident descents and Line Elite 30 carbon wheels with a 108-tooth Rapid Drive hub for quick acceleration when you need it most.
The final word
This is a beast of a mountain bike. You get hot new suspension technology normally reserved for the most expensive bikes, and you get it on a fresh new frame. With Slash 9.8, the faster you go, the better it rides, so giddy-up.

Sizing & Tech
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local retailer.
