Specialized’s all new 2009 Stumpjumper puts together a carbon fiber frame with frame specific BRAIN suspension technology for both front and rear suspension.  Get the full run down in the video (there’s a bit of audio static…sorry), and check the “more” link for lots of photos and info…
Like the new Epic, the 2009 Stumpjumper uses a new Specialized-developed fork putting their BRAIN technology in the front and rear.  For a 120mm travel bike, it’s pretty light at around 26lbs…and likely you could build it down around 23 if you really tried.
From a distance, it’s hard to tell this is even a carbon frame, but up close you can see the fiber tone on the mostly nude frame.  One thing that seems to be slightly dated in the design is the lack of a one-piece rocker arm.  Most brands are moving to a one-piece design to increase stiffness and reduce weight, my guess is this will be an upgrade for 2010 models.
The BRAIN sensor is located as close to the rear axle as possible, and you can see how the chainstays flare out at the back to accommodate the cassette and disc.
The tapered headset keeps the front end stiff, and the Avid Ultimates provide stopping power.  Altogether looks like a great package for backcountry, all day rides.
