Yes, the new Women's Stumpjumper ST 27.5 comes as an alloy version, and it may be the most radically designed alloy bike ever made. And with new tube shapes, an asymmetrical design, and the snappy handling that the 27.5 platform is known for, this bike is sure to exceed your expectations of how a trail bike should ride.

Our 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, we had to get to work on dialing-in the materials, shapes, and the layout.

We continued down the suspension path with a Women's Rx Tune that gives both the fork and rear shock a custom tune specifically for female riders. Suspension performance is highly dependent on frame, wheel, and rider size, so we use our Women's Rx Tune 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—we developed a specific Rx Tune for each platform and rider size. So, no matter what, you'll get perfectly linear suspension.

Steps were also taken to make this bike easy to live with. Threaded bottom brackets make a triumphant return, and we made room for up to a 3.0' tire. You're also free to run whatever aftermarket rear shock you want, since we're using standard metric shocks. And 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 130mm of travel, and wide alloy wheels.

  • The all-new alloy Women's Stumpjumper ST frame features an M5 alloy front- and rear-end, an asymmetrical design, and our 27.5 Trail Geometry, so it's both capable and comfortable.
  • The X-Fusion Metric rear shock features rebound adjustment, lockout, and our coveted Rx Trail Tune to ensure you're getting the most out of your Stumpjumper ST.
  • A RockShox Recon RL provides 130mm of travel up front, and it lets you adjust both rebound and lockout.
