Some hot info bullets from Specialized about the new Stumpjumper:
- Three versions of the new Stumpjumper give every kind of rider the best bike imaginable. The Short Travel (or ST) is snappy and nimble, while the Stumpjumper rides fast and planted. And for anyone that eats and sleeps gravity riding, they've brought back the EVO in all its slacked-out glory.
- The new Stumpjumpers have added stiffness to the frame, making it an even more capable descender. Extensive field-testing was performed to examine the connection between a rider's hands and feet in order to fine-tune the front-end stiffness. And the result is a bike that feels like it's riding on rails.
- The sidearm design directly connects all three mounting points of the rear-end and shock to the frame, and this creates a significant increase in both stiffness and performance over bumps. More explicitly, frame flex has been minimized when the rear suspension is active. The design makes it one of the lightest trail frames on the market.
- Bike suspension is a marriage between the frame kinematics and the shock, and the new design was able to rely more on the frame kinematics and less on the shock damper to perfect the Stumpjumper's ride quality. It is supple over small bumps, yet it possesses a firm mid-stroke and exceptional bottom-out support. This is the suspension that makes the Ultimate Trail Bike.
- The Flip Chip allows you to change the frame geometry with ease, all to support your riding style. There are two settings, High and Low, and when you "flip the chip," you effectively change the bottom bracket height by 6mm and the head tube angle by half-a-degree.
- In regards to cable routing, full tubes can be found throughout the carbon frame, so all you have to do is push the cable housing and it'll come out the other end. No more lazy loop, hidden stashes of magnets, pokey spokes, or pillows to cry in.
- The new chainstay protector makes the drivetrain virtually silent, and it pretty much makes chain slap a thing of the past, too. The nubs on this protector disrupt the slap of the chain and this reduces the overall movement and sound of the chain.
- The SWAT™ Down Tube Storage takes everything we loved from the last generation and makes it sleeker and lighter, while also adding 20% more volume.
- Ultimate Adjustability. All of the configurations use standard stroke and eye-to-eye metric shocks, so you won't find Shock Block anywhere. They brought back the threaded BB system, and both 27.5 and 29 frames can fit up to 3.0" tires, now. You'll still want to check with your fork manufacturer to make sure a high-volume tire can fit, but this should be music to everyone's ears.
