The Session 9 is a rowdy and ready downhill mountain bike with a robust alloy frame and high-pivot suspension design that keeps you nimble, planted and blazing-fast on even the most punishing runs. It’s built with Trek's best DH suspension package, a high-end drivetrain and powerful SRAM Maven Ultimate 4-piston brakes.
It's right for you if...
You. Love. Speed. And you’re looking for a beefy DH bike that’s built to keep up. You want a smarter, faster suspension design that keeps you in control, and you want the top-of-the-line fork, shock and brakes.

The final word
The Session has always been the go-to DH bike. Now it's more of a ripper than ever thanks to the suspension design that delivers more traction, speed and virtually no pedal kickback. Our best model gives you a top-of-the-line fork, shock and brakes, too.
