2020 Specialized Stumpjumper 29

We've heard it all before: 'This bike's for going fast, that one's for having fun.' 'This one pedals well, that one shreds.' Why not make one bike that does everything well? Well, we did
Add to cart

The Stumpjumper 29 combines the amazing ride quality and precision of our alloy sidearm chassis with plush RockShox suspension and a 12-speed SRAM SX Eagle drivetrain. Bottom line: It's a bike that outrides both its price tag...and bikes costing much more.

  • Alloy, sidearm frame design offers balanced stiffness and precise handling.
  • RockShox Deluxe Select rear shock features our Rx Trail Tune, ensuring that your frame, shock, and fork are perfectly in tune with one another.
  • RockShox 35 Gold RL fork offers smooth suspension in a stout package that includes a suspension lock-out to help tame the climbs.
  • SRAM's 12-speed SX Eagle groupset features a wide gear range that delivers climbing and shifting performance in spades.
  • Roval 29er wheels roll over obstacles and maintain momentum with ease.
