Specialized Stumpjumper Comp Alloy 27.5" 12-Speed Mountain Bike 2019
Bringing a new asymmetric frame shape to an alloy construction, this Stumpjumper Comp 27.5" Mountain Bike features the efficient and high-performing 12-speed SRAM NX Eagle groupset, ensuring that your hands, feet and body are working perfectly in balance to keep handling predictable and sharp. Front and rear FOX FLOAT suspension absorb the hits and soak up rough trails that can kill speed, so that you can carry momentum through any section. The 27.5" Roval Traverse wheels are nimble and responsive - easy to handle through technical turns, sharp to respond when you need acceleration and fast on the climbs.
Featuring much of the components and tech that are found on the top line models, this is a lot of bike for the price tag. An all new ribbed chainstay protector essentially silences the drivetrain, easy cable routing reduces maintenance and with the Flip Chip it's easy to fine-tune the geometry to lower the centre of gravity for rowdy descents. When the conditions are unpredictable and the weather takes a turn you can trust the SRAM Guide R hydraulic brakes to inspire confidence.
Features
- The FOX DPS Performance rear shock features the Specialized Rx Trail Tune, ensuring that no matter the wheel or frame size, your bike is dialled-in perfectly
- SRAM's 12-speed NX Eagle groupset features a wide gear range that delivers climbing and descending efficiency
- SRAM Guide R hydraulic brakes
- Adjustable dropper seatpost lets you set the position for comfort on harsh descents
- Easy cable routing for reduced maintenance
