2025 Trek Slash SE Gen 5 – Project One Earth & Air

The 2025 Trek Slash SE Gen 5 is a limited-edition enduro machine built for riders who live for speed, big sends, and terrain that punishes lesser bikes. Every single one wears a one-of-a-kind Earth and Air Project One paint scheme — no two are alike. Underneath the art is a race-ready platform: Flight Attendant intelligent suspension, a fully wireless SRAM GX AXS drivetrain, and a RockShox ZEB Ultimate fork with 38 mm stanchions that laughs at rough trails.

Whether you’re pinning laps at the bike park or charging natural enduro terrain, the Slash SE Gen 5 is ready to be the fastest, smartest bike you’ve ever ridden.
