The 2024 Trek Session 8 R2 is available at Biket, South Africa’s approved Trek Bikes online store. This downhill MTB features serious 200 mm suspension travel, 29” wheels and a tough alloy frame — engineered for high-speed descents, technical terrain and maximum control when the trail gets rowdy.

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.

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 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 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.
