Recommendations and Warnings

Cane Creek recommends only trained suspension technicians perform service on all suspension, using all required tools and following all proper procedures. Anyone without access to the proper equipment or with any concerns on the procedures should defer to an authorized Cane Creek service center for service. Improper service can result in loss of performance or suspension failure.
All Cane Creek shocks have pressurized nitrogen and oil, even coil shocks. Follow the service procedures exactly as written to avoid possible injury or harm to the suspension. Always wear eye protection while performing suspension service.

Please dispose of all waste products and materials through proper channels to avoid contamination of theĀ environment.

Any damage or issues resulting from improper service will not be covered by warranty. If you have a shock still in its original warranty period and do not wish to void your warranty, please contact an authorized Cane Creek service center.

These service instructions cover the basic service procedures using standard service kits. If your suspension requires parts beyond standard replacement parts – shaft, damper tubes, end eyes – please consult yourĀ authorized Cane Creek service centerĀ or contactĀ us at ourĀ Cane Creek Support Center.

Service Notes

The Kistuma Air and Coil share many service steps. Additionally, the Standard and Trunnion variants of both models have identical service procedures other than where to clamp the cylinder head.Ā Some images in these instructions may not be identical to the the valve body or outer damper tube on the Kitsuma Coil, but process is the same for the shock in the image and the shock on your bench.

Best part of being a part of the Cane Creek family: Ā It’s very refreshing to work for a small, tight-knit company where we all share the same passions and to develop new products that make cycling better for everyone.
What youā€™ll find me doing on the weekends: Obviously riding bikes, but also wrenching on bikes or cars, exploring the mountains, and watching F1 races.
How I got here (at Cane Creek): Feeling pretty unfulfilled with a corporateĀ engineering job, I happened to see that Cane Creek was hiring. I jumped at the opportunity to get my hands dirty working on the latest bike tech and was fortunate enough to be offered the position.
