It's right for you if...
You practically live at the downhill park, and want a fast, traction-packed DH bike that can handle your gnarliest runs thanks to a suspension design that keeps you in control all the way down.
The tech you get
A burly alloy frame, 200 mm rear travel with a FOX DHX shock, 200 mm RockShox Boxxer Select with plush Charger RC damper, powerful Code R 4-piston brakes and a SRAM GX 7-speed drivetrain.
The final word
The Session has always been the go-to DH bike. Now it's more of a ripper than ever thanks to a new suspension design that delivers more traction, speed and virtually no pedal kickback.
favorite_borderWhy 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 that 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
All speed, no hang-ups
Session’s high-pivot design results in a rearward axle path that lets the back wheel move with the rearward force from bumps, not against it. On the trail, it feels like smoother suspension that maintains more forward momentum and provides more grip.
Rock the mullet
Session comes stocked for speed with 29er wheels, but party-in-the-back riders can run a mixed setup with a 27.5˝ rear wheel, or even 27.5" front and rear for more agility.
Tune for your trail
With Mino Link adjustments on both geometry and suspension, you can easily tune your Session to a progressive feel for racing days or dial it back for park days.
When it comes to DH bikes, your reach affects your fit and ride quality far more than seat tube length. We’ve based Session’s sizing on reach to ensure you can find the setup that’s right for you.
Size-specific chainstay length
The chainstay length, or rear centre, grows as the frame reach grows so you get balanced weight distribution no matter your frame’s size. High-speed control and big mountain fun for everyone.
Route it your way
Run your cables in whatever custom variation you prefer: externally for easy replacement or internally to prevent snags and hang-ups.
Hitch without worry
Full-coverage armour helps prevent down tube damage from trail debris and makes for worry-free shuttling on tailgates and chair lifts.
