Session AL frameset gives you an awesome 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.
- 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 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
