Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Trek Session AL MTB Frame Set in Deep Dark Blue to Alpine Blue Fade

Season:2026

Brand:Trek

Code:37959BLU

The Session AL frame set provides an incredible foundation for building your ideal downhill machine.

The new high-pivot suspension design keeps you nimble, planted, and blazing-fast on even the most punishing runs. Its burly alloy construction handles gnarly and technical trails with ease.

This frame set is a great foundation for your dream downhill build. The new high-pivot suspension design delivers more traction, more speed, and virtually no pedal kickback.

It features a burly alloy frame and 200 mm rear travel with a Marzocchi Bomber coil shock, including a 226.7 kg spring. The FSA Orbit headset includes adjustable fixed-angle cups. It can be run with 29" wheels, 27.5" wheels, or even mullet style with a 29er in front and 27.5" at the back.

Features:

  • 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.
  • The Marzocchi coil shock delivers a supple feel with minimal stiction and consistent performance on long, rowdy descents.
  • This new downhill sizing system is based on reach, not rider height, which is the most important factor in a great downhill bike fit.
