Specialized Stumpjumper ST Expert 29" Mountain Bike 2019

Comfortably shred the rowdy stuff and still hold the wheel of your XC chums when the trail goes uphill with the Specialized Stumpjumper ST Expert 29" Mountain Bike; a ride that can genuinely lay claim to being capable of doing it all. The slightly steeper geometry delivers precise handling and responsiveness when you need to make sharp adjustments and tackle tight turns and combined with shorter RockShox front and rear travel, this bike will hold speed in all areas.

Improved stiffness thanks to new materials and tube shapes delivers better power transfer and helps to ensure that the balance between hands and feet is optimised, so the bike always feels stable. A new sidearm design keeps the front and rear connected and stiff, especially when the rear shock is active, and yet overall the weight is down, making this one of the lightest trail bikes on the market.

Should you need it there's room for a 3.0" tyre and you can drop the centre of gravity and slacken off the geometry a touch to suit your ride style. Chain slap on bumpy ground has been eliminated thanks to a new ribbed chainstay protector that more or less silences the drivetrain and with fully tubed internal routing it couldn't be easier to change cables.

The SRAM GX1 Eagle drivetrain is lightweight, high-performing and durable in all conditions so that your gear shifting is always crisp and the expanded range is optimised with a 10-50t cassette and 32T chainring so that you always have the perfect gear for the terrain. Rolling on Roval Traverse carbon 29 wheels, this lightweight bike will eat up the terrain, hold momentum and handle predictably - it's ready to race and ready to shred.
