Specialized Stumpjumper ST 29 2020 Full Suspension Mountain Bike Black Information

Season : 2020

Brand : Specialized

Code : 93220-76

Snappy and nimble, efficient and capable; the Stumpjumper ST Alloy brings the uncompromising performance of the Stumpjumper to an affordable price point.

Big on performance, small on pennies. When it comes to the big hits, there isn't much better than alloy for soaking it up without a scratch. And thanks to the M5 alloy, there isn't much of a weight sacrafice either. The ST Alloy also features the same innovative sidearm design that can be found across the Stumpumper frame. The asymetrical design means for a better handling bike whilst reducing the weight.

The Stumpjumper was designed for total control. The rear shock features RX Tune tech-each shock is tuned to be perfectly paired with the kinematics of the bike, meaning that you get perfectly balanced suspension. The front forks also provide you with 130mm of travel to keep you in control over the rough stuff. You've also got a TranzX dropper post to increase maneuvaribility on the descents. Combine this with the large 29er wheels that eat up and spit out all obstacles you put in its way, and you've got a fun, confident ride. 

The SRAM SX Eagle drivetrain and shifters provide you with smooth and accurate gear shifting in a simple-to-use package designed for MTBers. 12 speeds with an incredibly wide 11-50t gear ratio means you have got all the gears you need and more. The Tektro hydraulic disc brakes also provide you with incredible stopping power and modulation in all conditions, so you can ride with confidence and brake less and pedal more.

  • Double-wall Alloy rims are smooth rolling and rugged
  • 2Bliss ready Eliminator and Purgatory tyres gldie over rough terrain
