Specialized Stumpjumper Evo Comp Alloy 29 Mountain Bike 2020
This Specialized Stumpjumper Evo Comp 29 Mountain Bike retains the recognisable attitude of it's ancestors and carbon siblings, and still has that unmistakable hunger to charge every feature on the trail, but this alloy build benefits from being gentler on the wallet. The long and low geometry pins the bike to the ground delivering top drawer traction and the Roval 29" rims plough through the gnarliest terrain with ease. The new sidearm design enhances control and stiffness by directly connecting all three mounting points of the rear-end and shock to the frame, so the bike climbs with surprising keenness.
The slacker head angle is less twitchy and delivers more confidence for pinning the descent, so you can carry more speed and flow better through the turns. A 12-speed SRAM NX 1X drivetrain has a 10-50t cassette and a small 30T chainring so that you've got plenty of gears when the climbs start rolling through or you want to spin back to the top of the trail. And when the trail falls away and you need to maximise body position, use the X-Fusion dropper post to get more weight over the back wheel.
Features
- SRAM Code R, 4-piston caliper, hydraulic disc brake
- Butcher Grid Trail 2Bliss Ready, 29" tyres complement the increased traction from the low geometry
- SRAM NX Eagle, 12-speed drivetrain
- Fox Float front and rear suspension
