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 Code RSC brakes.

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.

A burly alloy frame, 200 mm rear travel with a RockShox Super Deluxe Ultimate DH RC2 shock, 200 mm RockShox Boxxer Ultimate fork with DebonAir+ spring and Charger 2.1 RC2 damper, Code RSC 4-piston brakes, SRAM X01 DH 7-speed drivetrain and carbon bars.

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. Trek's best model gives you a top-of-the-line fork, shock and brakes, too.
