29-inch wheels

The reduced rolling resistance and larger footprint of 29-inch wheels inspires confidence climbing over obstacles and helps you cover ground efficiently.

120mm VPP™ travel

VPP™ suspension can be optimized to strike the right balance between pedaling efficiency and all-out bump chomping prowess. That means wherever you see "VPP™" you know it's tuned to perform exactly how it should for the purpose it's designed for.

Glovebox

Place your ride essentials securely beneath a new high-quality latch and panel in the downtube. The Glovebox comes with a fitted Tool Wallet and Tube Purse, tailored for the frame to keep your tools close to hand.

Full carbon C and CC frame

Carbon CC frames use the very best materials and production processes available, while Carbon C frames offer the same great features while adding a little more weight to save a little $. Both versions are made in our own factory, are just as strong and stiff as one another, and have a lifetime warranty.

Made to last many lifetimes

The legendary fit, finish and quality construction put this into a league of its own. The frame, bearings and optional Reserve wheels come with a lifetime warranty and any service is easy to do with our Rider Support pledge.

SRAM Eagle Transmission - stronger, better shifting, wirelessly

The next generation SRAM Eagle Transmission spec'd on our CC-carbon models is a radically robust, fully integrated and interdependent wireless transmission. Built around the universal constant of the wheel axle itself, the hangerless attachment mounts directly to the frame for a stronger connection and the derailleur provides unprecedented reliability in case of impact. Shifting under load is made possible due to a combination of X-SYNC technology and cassette mapping, creating seamless shifts even during your hardest power output. The new AXS Pods are ergonomic and customizable, so shifting gears is light and intuitive. It's simply the most advanced transmission and nearly as tough as you are.

Fit for smaller riders: Proportional Geometry and frame stiffness tune

Chainstay length and seat tube angle are matched to the frame size (STA steepens and rear center grows as frame size increases) so that every rider, no matter what height, gets the same balance of geometry and handling characteristics.

We tailor stiffness for every size to make sure every rider gets the same ride quality. We take out carbon material as the sizes get smaller where less stiffness is needed. Smaller riders require less reinforcement on frames, and that's remedied with our size-specific frame stiffness tunes.

Frame Sizing

If you're on the cusp between the recommended height range of two sizes, the absolute best thing is to try to ride them both. At a minimum, check the stack/reach measurements on your current bike and compare it to the new model you are looking at to get an idea of a fit you are already comfortable with. If riding the bike is not an option, consider the following.

The Joplin is available in sizes extra small - medium (XS-M).
