Trek Slash 8 Mountain Bike 2021
For those seeking a ride that can take on steep lines and cruise the rowdiest hits, the Trek Slash 8 Mountain Bike delivers on all counts. With a pedigree history, the Slash has seen countless wins on the Enduro World Series circuit and is sure to please those looking for a confident, race-inspired feel. Fitted to the Alpha Platinum Aluminium frame is a high-value parts list, designed to keep you rolling season after season. The 29” wheels see unrivalled pace through rough terrain, and when combined with the burly 160mm of rear travel, ensure performance both inside the tape and out.
To protect the robust frame, a dual downtube guard prevents rock strikes and shuttle damage, and for those looking to ride pack-free, an internal compartment allows for hidden downtube storage for your tools and nutrition. Knock block is featured but in an all-new guise. The removable design provides a wider turning radius for switchback turns, yet still keeps your frame, cables and hoses safe from damage in the event of a crash.
Durable and season-proof, the parts specification blends value and performance to deliver a capable ride that doesn’t blow the budget. Bontrager in-house components offer superb performance, with this build featuring their traction-focused XR5 Team Issue tubeless-ready tyres and robust Line Comp 30 wheelset. A RockShox Super Deluxe controls the 160mm of supple rear travel, while the proven Lyrik Select+ fork delivers sublime traction through gnarly terrain. Four-piston SRAM Code R brakes see ample stopping power for this ride's supreme pace and instil confidence on the steepest gradients.
- A sleek internal storage compartment gives you a versatile spot to stow tools and gear
- A second down tube guard has been added to better protect your frame from shuttle-related damage
- Equally at home between the tape and in the rugged wild
- Removable Knock Block has a bigger steering angle to keep cables and hoses safe without sacrificing the turning radius
- The 34.9 mm diameter post is stronger, more durable, and moves up and down faster
- Fast-rolling 29” wheels carry speed over rough terrain
- 170mm RockShox Lyric Select+ fork and 160mm Super Deluxe Ultimate shock deliver supple traction and big-hit performance
- Tubeless-ready Bontrager Line Comp 30 wheelset with Rapid Drive 54t engagement
