The Session 8 is a downhill mountain bike with a burly alloy frame and high-pivot suspension design that keeps you nimble, planted and blazing-fast on even the most punishing runs.

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.

A burly alloy frame, 200 mm rear travel with a Marzocchi Bomber 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 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.

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
