Juliana Joplin 4 C GX AXS Complete Mountain Bike – Women’s 2025

The Juliana Joplin 4 C GX AXS Complete Mountain Bike is the go-to choice for dirt lovers who are focused on having quick fun above all else. It’ll happily pedal all day on your favorite XC loop, but this 29er is much more than a one dimensional specialist – it’s a kaleidoscope of gravity assisted trail capability, making it feel like five bikes in one. It has the latest VPP® suspension design, size-specific rear ends, Glovebox™ in-frame storage, and the amazing SRAM GX Transmission wireless drivetrain. You only get to ride one bike at a time, and a Joplin always the right choice.

Carbon C Frame
–
Juliana's C Carbon frames use the same proprietary processes of the highest spec CC Carbon frames to meet the same legendary strength and stiffness standards. But the use of a different grade of carbon material results in a minimal weight gain.

Travel
–
130mm Front / 120mm Rear

Wheel Size
–
29"

Lower-Link Mounted VPP® Suspension
–
VPP is based on the patented principle of having two short links rotating in opposite directions. This system provides huge design flexibility, allowing Juliana to manipulate shock rates to the intended purpose and character of each model; from short travel endurance bikes to World Championship winning DH machines. This redesign mounts the shock lower on the bike, making for an even better ride quality.

The Glovebox™
–
Seal whatever you want to carry on your ride inside your downtube. Secure and easy to access, the Glovebox™ has a Tool Wallet and Tube Purse inside, to help organize your stuff too. Simply cavernous!

Proportional Chainstay Lengths
–
With rear ends that match the size range, this bike's geo and ride quality is the same for all riders.

Integrated Flip Chip for High/Low Geometry Adjustment

  Biking Type

  Mountain
  Mountain bikes are built for tackling rough terrain with frames made of durable materials like aluminum or carbon fiber, ensuring stability and maneuverability. They feature suspension to absorb impacts from rocks, roots, and drops, providing a smoother ride.

  Used For

  Trail

  Trail bikes are the quintessential “mountain bikes.” If you’re heading into the woods expecting to do it all on two wheels – climbing, technical sections, AND fun descents – you’re looking for a trail bike.

• Suspension:
  Full Suspension

  More

  Suspension

  Full Suspension

  Engineered to tackle the most challenging terrain with enhanced comfort and control. Unlike hardtail bikes, full suspension bikes feature both front and rear suspension systems that allow the wheels to move independently from the frame.

• Frame Material:
  Carbon

  Frame Material

  Carbon

  Carbon is a composite frame material. Unlike metals, carbon is composed of fibrous strands woven into a grid and bonded with epoxy. Carbon is favored by many for its lightness and stiffness but its complexity in fabrication makes it the most expensive option.

It also features the first ever tool-free cage and clutch assembly – so it’s both removable and upgradable too.
