Technical Specifications
The Stumpjumper FSR Expert adds a Specialized Command Post, sweet 29
  • Specialized Command Post is a 3-position adjustable-height seatpost with remote lever for on-the-fly changes to riding position, 125mm travel
  • Fully manipulated M5 alloy 29er frame uses 130mm of travel, lightweight ORE tubing, and sealed cartridge bearing pivots to turn rock gardens into Zen gardens
  • RockShox Reba RLT 130mm-travel 29er fork with tapered alloy steerer, adjustable rebound/compression/threshold, and 20mm Maxle thru-axle delivers lightweight trail performance
  • Specialized/Fox Brain rear shock with Brain Fade, remote Trail Tune inertia valve, and adjustable rebound lets riders dial in the perfect blend of pedaling efficiency and bump compliance
  • DT Swiss 520SL 29" rims, spokes, and rear hub combine with a Specialized Hi Lo front hub and 20mm thru-axle to create a wheelset that's strong enough to handle complex singletrack, yet light enough to make the climb out effortless
