The Slash 8 is an enduro mountain bike that's built for pressing the send button again and again. It's built on a high-pivot platform with 170 mm or front and rear travel that boosts traction for punchy climb stages and keeps stability a priority when you point it straight down. A mixed set-up with a 29˝ front and 27.5˝ rear wheel keeps handling playful, and it comes equipped with a Shimano XT drivetrain for clean shifts no matter where you ride.

You want an enduro bike that keeps pedalling efficient on the ups and slays on the downs. The added traction from a high-pivot bike is appealing, but the stability on descents is really what takes the cake.
