      Trek Slash 8 Full Suspension Mountain Bike 2023

      Slash 8 is an enduro mountain bike that rolls on fast 29er wheels and floats on plush RockShox suspension with SRAM's 12-speed GX Eagle handling drivetrain duties. An aluminum frame with fresh new tech and tough alloy wheels push this bike into the sweet spot for all-around rippers.

      It's right for you if...

      You want a big bike with big wheels to roll over big things and send big hits. You might enter some enduro races, but you mostly just want to rail sketchy descents faster than anyone else in your crew.

      The tech you get

      An aluminum frame built for harsh riding with a threaded bottom bracket, dual downtube guards, Knock Block 2.0, and 160mm of travel with a RockShox Super Deluxe Select+ shock for long descents and 170mm RockShox ZEB Select fork. Plus, a SRAM GX Eagle drivetrain with an extra-low 52-tooth gear, Code R 4-piston brakes, and completely tubeless Line Comp 30 wheels.

      The final word

      Slash 8 puts serious enduro performance within reach with smart choices on spec that won't empty your wallet. The aluminum frame, burly suspension, and 1x12 Eagle drivetrain makes for a ride that's equally at home on the race course and on a big, backwoods session.

      Why you'll love it

      1. A sleek internal storage compartment gives you a versatile spot to stow tools and gear
      2. We added a second down tube guard to better protect your frame from shuttle-related damage
      3. It's equally at home between the tape and in the rugged wild—Yes, Slash is a race bike, but it's ridiculously fun on gnarly trail rides, too
      4. New, removable Knock Block has a bigger steering angle to keep cables and hoses safe without sacrificing turning radius
      5. Wider seat tube, wider dropper—the 34.9mm diameter post is stronger, more durable, and moves up and down faster
