The design goal for the new Stumpjumper was simple, build the ultimate trail bike, one that feels telepathic. And it turns out that this feeling all comes down to stiffness. Think of it this way: when the frame's telling your hands one thing and your feet another, your brain gets confused with the imbalance and the bike feels unstable. In order to fix this, Specialized had to get to work on dialling-in the materials and shapes.
Continuing down the suspension path with a custom Rx Trail Tune on both the fork and rear shock with 120mm travel in the rear and 130mm up front. Suspension performance is highly dependent on frame, wheel, and rider size, so Rx Tune is used to get each bike to land in the middle of the adjustment spectrum, and this gives you the biggest possible range to fine-tune your ride.
Steps were also taken to make this bike easy to live with. Threaded bottom brackets make a triumphant return, and theres room for up to a 3.0' tyre. You're also free to run whatever aftermarket rear shock you want, with a new standard metric rear shock measurement.
Customization is furthered with a Flip Chip that lets you to dial-in your Stumpy to your riding style. Switch it from High to Low and it drops your bottom bracket 6mm and slackens the head tube by half-a-degree. Little details also jump out to surprise you, like a newly designed ribbed chainstay protector that makes chain slap a thing of the past and nearly silences the drivetrain.
The build here is no-nonsense with a focus on dependable, high-performing parts, like Shimano SLX front and rear derailleurs, Tektro Gemini disc brakes, a RockShox Recon RL fork with 130mm of travel, a custom X-Fusion 02 Pro RL rear shock with 120mm of travel, and wide alloy wheels.
