Trek Frame set Session AL F/S Deep Dark Blue to Alpine Blue Fade

The Session AL frame set offers you a great foundation for building the downhill machine of your dreams. The new high-pivot suspension design ensures agility and stability, making you lightning-fast even on the toughest courses, while the robust aluminum construction easily handles rough terrain.

Trek offers you a robust aluminum frame and a FOX DHX shock with 200 mm of travel. The FSA Orbit headset comes with bearing cups with an adjustable head tube angle. The frame can be ridden with 29" or 27.5" wheels and even as a mullet with a 29er front and 27.5" rear.

1. The new suspension layout with a high pivot and idler improves traction, supports higher speeds, and reduces pedal kickback for more stability.
2. Eliminating pedal kickback increases the stability and controllability of the bike on brutal descents and especially when landing jumps and drops.
3. The high pivot ensures an optimized rear wheel path, allowing you to travel with more speed and overcome obstacles more efficiently.
4. Easy adjustment of progression at the lower shock mount – 20% for smooth park runs, 25% for high race efficiency.
5. Our new size system, specifically developed for downhill bikes, is based on reach, the most important factor for a great DH fit.
