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 the 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.

Service Notes

This service covers changing stroke ONLY on a new DBair IL shock. As o-rings are considered new as part of this service, they will not be replaced. If this stroke change is being done on an older shock, a full 100 hour service is recommended.

The stroke change procedure is the same for Standard and Trunnion mount shocks. A Trunnion shock is used in these photos. 

Service Kits

No service kits required. Please consult your authorized Cane Creek service center or contact us at our Cane Creek Support Center to detemine which stroke reduction parts are needed for specific stroke changes.

General Prep

Clean shock. Record tune if desired. Remove hardware on lower end eye if wider than the outer air can.  Remove valve cap. Bleed air from shock using shock pump. Be sure to depressurize shock slowly to avoid trapping air in the negative chamber.

Air Spring Disassembly

Step 1 – Outer Air Can Removal

Clamp shock in vise using soft jaws. Remove air can circlip using a pick. Flip the shock in the vise. Using strap wrench, twist and apply downward force to free outer air can. Work outer air can past end eye to remove completely. Note any air volume reduction.

Step 2 – Freeing Inner Air Can

Reclamp shock. Align teeth on Air Seal Head Tool with grooves on air seal head. Unthread air seal head/inner air can from end eye. Splash oil may be present. Slide inner air cap up shock body to expose shaft.

Step 3 – End Eye Removal

Slide inner air cap up shock body to expose shaft. Clamp shaft in 8mm shaft clamp with end eye up. Remove end eye using 1/2″ crows foot. Remove any existing stroke reduction. No need to remove shim or bottom out bumper.

Air Spring Reassembly

Step 1 – End Eye Install

Install any required stroke reduction with chamfered edge towards end eye. Apply blue Loctite (243) to shaft threads and end eye threads. Thread end eye onto the shaft. Clamp shaft into vise with shaft clamp. Using 1/2″ crowsfoot, torque end eye to 4.8 Nm. Clean any extra Loctite from shaft and end eye.

Step 8 – Inner Air Can to End Eye Install

Clamp end eye in vise. Add 5 ml of Royal Purple to end eye. Add PolyLube grease to threads on inner air can. Thread inner air can onto end eye. Torque to 22.6 Nm using Air Seal Head tool.

Step 9 – Outer Air Can Install

Clamp valve body end into vise. Work outer air can gently past o-rings. Note correct orientation of air can. Final o-ring will be tight. Strap wrench may be necessary. Engage Climb Switch to aid installation. Ensure valve is oriented away from Climb Switch. Install outer air can retention clip.

Final Testing and Set Up

Air up shock to at least 100 psi. On hand dyno or bike frame, slowly cycle shock and listen for negative volume chamber to pressurize. Using soapy water and dunk tank, test for any possible air leaks. Install valve cap. Reinstall hardware if removed.

Name: Reed Mann
Position: Design Engineer
Year started: 2022
Best part of being a part of the Cane Creek family:  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 you’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 corporate 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.
