I've been trying to figure out how to best set up my new shocks that are multi adjustable for compression, dampening and rebound, but haven't really found much online.

I finally found some info in a BGM shock manual that was in German. I used google translate to translate the pages on setting up the shocks and adjusting. This should be enough to apply the same principles to my SIP shocks. Plus there is a little blurb about adjusting shocks in a SIP document I found.

Both documents attached below.

If anyone else has some tips for adjusting these types of shocks, please share!

So i've attached photos pointing out what I believe each adjustment is. Let me know if I've got these wrong. Spring Preload Compression Damping Rebound Damping

Hopefully someone will boil it down a bit. 🙂 At least now I know which one is compression and which one is return! Thanks!
