Check out what's new in the wrecking crew's test fleet: an S-Works Stumpjumper 29er. This is the top-of-the-line trail 29er bike for Specialized. Watch for the full review in the December 2012 issue. For now, take a sneak peak at the highlights in this week's "Trail Testing."
Pulling out the stops:
Specialized builds their S-Works bikes the same way a top-level racer would get them... with nothing held back, and no expenses spared. The S-Works Stumpjumper sports 5 inches of travel front and rear, 29-inch wheels, and a whole lotta carbon throughout the build.
The heart of the bike:
The Brain Fade shock is the heart of the Stumpy's suspension system. The shock has a remote reservoir that automatically senses whether inputs are coming from the rider or the ground, and adjusts for the perfect amount of damping without any on-the-trail input needed from the rider. The build kit is top of the line, sporting a full XTR kit from Shimano.
Even more automation:
The rear shock on the Stumpy uses a proprietary design called Autosag, which was a joint project between Fox and Specialized. The shock automatically knows how much pressure should be in the shock with the push of a button. While the feature will eliminate guesswork for most riders, it also allows just as many fine-tuning options as a standard shock. The drivetrain utilizes Specialized's carbon cranks and a PressFit 30 bottom bracket, as well as a custom XX spider and chainrings.
We want to keep this one:
The wrecking crew has plenty of products to test, and when we get a bike like this one, we like to experiment with it a bit. We recommended Specialized's Blacklight post when we reviewed it several months ago, and it comes stock on this bike. However, the all-new Mavic Crossmax SLR 29er wheels are a substitute for the carbon Roval wheels that come with this bike. While we don't have enough time on them yet to make a full recommendation, all systems are "go" so far.
Smart designs and clean lines:
That's what this bike is all about. Keep your eyes peeled for the full review in the upcoming December, 2012 issue!
The wrecking crew strives to put as many miles as possible on each test bike before we write a full review. Watch for the full write-up on this bike in the coming pages of Mountain Bike Action.
