Trek Session 9 X01
Details
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 our best DH suspension package, a high-end drivetrain, and powerful Code RSC brakes.
WHY YOU'LL LOVE IT
- New suspension layout with a high pivot and idler pulley increases traction, carries more speed, and reduces pedal kickback for more stability
- Virtually zero pedal kickback means you'll stay confidently planted and in control during descents — especially when landing jumps or drops
- The high pivot design delivers a more efficient rearward axle path so you'll carry more speed and your wheel won't get hung up on obstacles
- Adjust your suspension progression by flipping the lower shock mount chip — 20% for plush park rides, 25% for racing efficiency
- Our new DH sizing system is based on reach, not rider height, which is the most important factor in a great downhill bike fit
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 TECH YOU GET
A burly alloy frame, 200mm rear travel with a RockShox Super Deluxe Ultimate DH RC2 shock, 200mm 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 FINAL WORD
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.
