Specialized Stumpjumper Evo Expert Mountain Bike 2022
Back in a new adjustable, hard-hitting guise, the Specialized Stumpjumper Evo Expert Mountain Bike is a versatile trail slayer that excels on high-speed trails. Built to perform in the rough, the 150mm of suspension copes admirably with the roughest of descents yet offers a firm, efficient pedalling platform for the climb back to the trailhead. Rolling on fast 29” wheels, this carbon fibre frame is lightweight and robust and features FOX Performance Elite level suspension for unparalleled traction on technical terrain.
Revised for this latest frame, the SWAT™ Door integration offers even more space to store your on-trail essentials such as pump, tube and tools. The suspension kinematics have also been revisited, and now channel Specialized’s longer travel offerings to offer improved performance on square-edged hits. A wide array of adjustments is on offer, with an eccentric headset cup and chainstay-mounted flip-chip offerings up to 2° of head angle adjustment to suit all rider preferences.
The spec is race-ready and features a high-quality SRAM 12-speed X01 drivetrain to deliver crisp shifting through the entire 10-52t gear range. SRAM Code RS brakes provide supreme braking power for steep, technical descending, and the Roval Traverse wheels are both lightweight and durable.
- Same 11m carbon frameset as seen on the S-Works model
- Redesigned suspension kinematics for improved on-trail performance
- Adjustable geometry to suit any trail, with six different settings and 2° of head angle adjustment
- Steeper seat angle for improved climbing characteristics
