That's why the Women's Stumpjumper Comp Carbon 27.5 goes above and beyond to provide you with the ride of your life. Every touchpoint is tailored for female riders, while the frame shatters every rule in the design book with a total disregard for proprietary nonsense, a revolutionary new asymmetrical frame, and custom shock tunes exclusively for women.
The design goal for the new Stumpjumper was simple - design a trail bike that feels telepathic. 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 dialing-in the materials, shapes, and the layout.
They started by creating their own mountain-specific stiffness test that examines the connection between a rider's a hands and feet, and then looked at the layout with Finite Element Analysis (FEA) to see where the biggest stiffness improvements could be made. This led to a big discovery: Bigger frames needed more front-end stiffness while the smaller ones were just fine. The same stiffness standards in the front triangle of the smaller frames have been kept, while reducing weight by about 20%. For the big frames, Specialized ramped up the stiffness by 20% and kept the same weight.
Focus was turned to the rear-end to see how the ride could be further improved. A radical new sidearm design was developed that crushes stiffness targets. By connecting all three shock mounting points in one structure, deflection was minimised when the suspension is active, and this greatly contributes to the incredible new feel on the trail. The new sidearm design also takes about 100 grams out of the rear of the frame.
Specialized continued down the suspension path with a custom Women's Rx Tune on both the fork and rear shock. Suspension performance is highly dependent on frame, wheel, and rider size, so Rx Tune was 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. Another focal point of the tune was matching the suspension characteristics between wheel sizes - a specific Rx Tune was developed for each platform and rider size. So, no matter what, you'll get perfectly linear suspension.
Steps were also taken to get rid of all the proprietary nonsense. Threaded bottom brackets make a triumphant return, room was made for up to a 3.0" tyre. You're also free to run whatever aftermarket rear shock you want, since they're using standard stroke and eye-to-eye dimensions. No AUTOSAG. No Shock Block. The SWAT™ box was also revamped, making it sleeker, lighter, and with 20% more volume, and customisation 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, slackens the head tube by half-a-degree, and shortens the reach by 5mm. 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 nubs on this protector disrupt the wave of the chain, like throwing a rock into the water to break the surface tension before jumping off a cliff. It's super cool.
The build comes with a list of components that deliver undeniable quality, like a Shimano SLX shifters, an XT rear derailleur, RaceFace cranks, Shimano SLX disc brakes, FOX front and rear suspension, and Roval Traverse 27.5 wheels. Meanwhile, every point that your body comes into contact with the bike has been tailored specifically for female riders with the inclusion of superlative kit, like a Body Geometry Myth Comp saddle, Sip Grips, and 750mm bars.

The asymmetrical, FACT 11m carbon fibre construction on the Women's Stumpjumper is lightweight, stiff, and ready to take on the trail. It's built off of a 27.5 Trail Geometry, so it's just the right amount of both capable and comfortable. And with SWAT™ integration in the down tube, a threaded BB, easy cable routing, and an all new chain silencer, it's ready for anything the trail, or you, throw at it.
