Trek Session
DH and bike-park specialists. Not an all-mountain trail bike.
Downhill race bike. Slack, long-travel, and unhappy if you try to pedal it like a Slash on a fire road.

Trail riders who want one Specialized and are willing to size by reach. Enduro-curious riders should look at Stumpjumper EVO or Enduro; XC racers at Epic.
The first S-sizing Stumpjumper: six frame lengths from S1 to S6 with short seat tubes, so reach and wheelbase pick your size instead of your inseam. Travel dropped to 130 mm rear behind a 140 mm fork, leaving the longer stuff to the EVO.

New Trek Session features adjustable suspension progression and is compatible with multiple wheel size configurations.
2021 Trek Session is a 200mm travel 29er downhill bike, with high pivot idler design, that can also be configured to run mullet or 27.5in wheels.
Featuring one of the lightest frames in its class, the 2022 Specialized Stumpjumper offers low weight, progressive geometry and cleverly-tuned suspension.
We put the Specialized Stumpjumper Expert through its paces, and see how it stacks up against both the competition and its Evo big brother.
