BikeYoke SJ01 Stumpjumper Adapter

The BikeYoke SJ01 is specifically designed for Specialized Stumpjumper frames manufactured between 2010 and 2015. It will not fit other model years or different frame brands.

No, the adapter is engineered to maintain your frame's original geometry and suspension kinematics. As long as you choose a shock with the correct eye-to-eye length and stroke, your bike's handling and ride quality will remain consistent with the original design.

Specialized often uses proprietary shock mounts that limit your replacement options. This adapter removes that limitation, allowing you to install standard aftermarket shocks that are easier to service, tune, or upgrade for better performance.

Installation requires standard bike tools, such as hex keys, to remove the existing yoke and mount the new adapter. You should also be comfortable with the process of removing and installing a rear shock, including properly torquing the mounting bolts.

While the adapter allows for standard shocks, you must still ensure the new shock matches the specific eye-to-eye length and stroke required by your Stumpjumper frame. Always verify the shock's physical dimensions to ensure it fits within the frame's space constraints before purchasing.
