The Session AL frameset is a great base for building the ideal downhill bike. Thanks to the new high pivot suspension design, the bike will be agile, fast and grip the ground on even the most demanding rides. Its rugged alloy construction can handle rough and technical trails with ease.
You're into downhill mountain trails and the occasional race. You enjoy lightning-fast descents and want a massive, high-traction DH frameset that you can fit with the parts you want to build your dream downhill bike.
- New suspension with a high-mounted pivot and embedded pulley improves traction, allows for more speed, and minimizes pedal kickback for better stability.
- Almost no pedal kickback keeps the bike nailed to the surface and handles beautifully on descents and especially jumps and drops.
- Thanks to the high-mounted pivot, the rear axle travel is more efficient, so you'll go faster and the bike won't scrape against obstacles.
- The Marzocchi spring shock ensures smooth suspension with minimal chatter and reliable performance on long and demanding descents.
- Our new DH bike sizing system is not based on rider height, but on reach, which is the most important factor in choosing a great fitting downhill bike.
A great foundation for your dream DH bike. The new high-riding pivot design improves traction, offers higher speeds and nearly eliminates pedal kickback.

TREK is headquartered in Waterloo, Wisconsin. The family-owned business was founded by Richard Burke in 1976, starting out in a small steel bicycle factory with just five employees. Within a few short years, the company caught on to bicycle trends and continued to grow. In the early 1990s, it began producing bicycles in a then-new material - Carbone. Today, TREK sets the trends in bicycle development and is also considered a leader in the processing of Carbone. Its proprietary processing technology, called OCLV, has been applied in production with many innovations for more than 17 years. TREK bikes have celebrated success at major world races and have been associated with names such as Lance Armstrong, Alberto Contador, Chris Lieto, Roland Green, Chris Eatough, Andrew Shandro and Travis Brown. TREK is a premium brand you can always rely on.
