Specialized Stumpjumper FSR Comp Carbon 650b review

http://ift.tt/2ggc14s

Specialized’s Stumpjumper FSR Comp Carbon family covers every possible modern trail bike base, including 29er and plus versions, but it’s a conventional cruiser rather than a radical charger.

A mid-range composite front end is mated to an M5 alloy back end, and the down tube features Specialized’s unique SWAT internal storage hatch under the bottle cage. The RockShox Monarch RT shock gets a bespoke ‘Rx Trail Tune’ and ‘Autosag’ side valve for easy set-up of the 150mm stroke.

The rear of the shock uses a custom cradle to connect to the shock driver yoke, which in turn connects to the U-shaped linkage of Specialized’s FSR kinematic. A curved seat tube and 148mm wide Boost rear hub allow super-short asymmetric chainstays, and gear and dropper post cables are all routed internally. The down tube sports a big protective plate in front of the PF30 bottom bracket shell and there are also chain guide mounts.

The tight grip of the SRAM GX rear mech and Race Face direct-mount chainring meant we never felt the need for a chain guide, though. The RockShox Yari RC fork is a seriously tough unit, while the Specialized Butcher and Slaughter tyres get reinforced Grid casings.

The 200mm front rotor on the size L and XL bikes amplifies the power of the SRAM Guide R brakes. Specialized’s bar and stem suit the trail character and the own-brand dropper is reliable, if eye-wateringly rapid in action. Specialized’s 29mm internal width wheels add tyre volume, but reduced spoke count affects stiffness.
