Frequently Asked Questions

Q: Do I need to re-valve my damper for The RUNT to work?

A: We recommend custom tuning your damper to better match the performance of the RUNT, but it’s not required. The RUNT works well as a drop-in and will be an improvement to your ride. Shim kits are available in our web store that come with shims to re-valve your rebound and/or your entire damper. Technical documents with instructions for re-valving your damper can be found here: Technical Documents

Q: Why do I need to send my RockShox Charger 2 or 2.1 damper to DSD for a Full custom tune?

A: We get this question a lot, so we made a video explaining why you’ll need to send your Charger 2 or 2.1 damper in to us for a full re-valve and also why this is recommended for the best RUNT performance. Watch the video here: DSD RUNT: Charger 2 Tune and Mods

Q: How do I send my fork to DSD for re-valving and install?

A: Fill out our Service Request Form and follow the instructions provided.

Q: Will the RUNT work with the Vorsprung Luftkappe?

A: There is not enough room in the air chamber for both the RUNT and the Luftkappe. The RUNT provides excellent small bump compliance while also vastly improving the mid-stroke support of your fork’s air spring, giving it a coil-like feel.

Q: Is The RUNT hard to install?

A: The RUNT is super easy to install. Follow the directions in our Quick Setup Guide.

Q: Will The RUNT work in any fork?

A: The RUNT is fork and travel length specific. The RUNT was designed to take up the maximum air volume in your fork leg based on the amount of travel. The RUNT body is designed to switch between two different travel lengths based on the piston that is used. If you want to change the travel in your fork, please send us an email to discuss options. Compatibility chart coming soon. Do not use a RUNT designed for a different travel length as this could cause serious damage or injury.

Q: What maintenance does The RUNT require?

A: The RUNT requires very little maintenance. About once a year you should do the following: Remove the air, and then remove The RUNT from your fork leg. Next remove the clip holding the piston at the bottom. Add a small amount of air to the high side and the piston will pop out. Grasp the O-ring on the piston with a paper towel between your thumb and for-finger. Pop off the O-ring and match it up at the hardware store. Put a small amount of Slick Honey on the O-ring. Add a small amount of Fox Float Fluid to the inside of The RUNT, and re-install the clip. Put The RUNT back in your fork and you are ready to go!

Q: Do you ship internationally?

A: Yes, we will ship anywhere. We do not currently have any international distribution, but eventually we will. Stay tuned.

Q: Do you sell to bike shops?

A: We do sell to bike shops directly. If you are interested in becoming a dealer, please fill out our Dealer Application.

Q: Why is it called The RUNT?

A: The RUNT gets its namesake from the original proof of concept that was made out of a rear shock damper body… The rear in the front.
