Trek Session AL 2024
The Session AL frame set gives you an incredible foundation for building up your ideal downhill machine. The new high-pivot suspension design keeps you nimble, planted and blazing-fast on even the most punishing runs, and burly alloy construction rolls with the punches on gnarly and technical trails.
It's right for you if...
You spend your days putting in laps on the mountain, and even racing from time to time. You live for blazing-fast descents, and want a solid, high-traction DH bike frame set you can spec with your choice of parts to create the DH bike of your dreams.
The tech you get
A burly alloy frame, 200 mm rear travel with a FOX DHX shock. The FSA Orbit headset includes adjustable fixed-angle cups. Can be run with 29" wheels, 27.5" wheels or even mullet style with a 29er in front and 27.5" at the back.
The final word
A great foundation for your dream DH build. The new high-pivot suspension design delivers more traction, more speed and virtually no pedal kickback.
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 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
