Specialized Stumpjumper Comp Carbon 27.5" 12-Speed Mountain Bike 2019
With a refreshed geometry, refined materials and fine-tuned tube shapes, the Specialized Stumpjumper Comp Carbon 27.5" 12-speed is a balanced mountain bike with sharp and predictable handling. The reliable components reduce maintenance and keep trail-fuss to a minimum, making this a highly capable bike at a price point that won't break the bank.
The frame has enough space for up to a 3.0" tyre, for particularly hectic conditions, and with the Flip Chip you can lower the centre of gravity by slackening off the geometry to suit your ride style. The internal routing uses full tubes inside the frame, keeping vulnerable cables well clear of trail grime and making feeding new ones a cinch. FOX Float suspension front and rear take the sting out of aggressive trail features and help to control the bike through fast turns and technical descents.
The 1x 12-speed SRAM NX Eagle groupset keeps maintenance low and has plenty of range to deal with the sharpest climbs and the SRAM Guide R hydraulic discs deliver high-performance braking no matter the conditions.
Features
- Ribbed chainstay protector stops chain slap and keeps the drivetrain quiet
- FACT 11m carbon frame is lightweight, stiff and trail-ready
- SRAM NX Eagle groupset is reliable in all conditions
- Roval Traverse 27.5" wheels are nimble and fast
