    When does the low speed and high speed compression work?

    My main question really comes down to hitting those small rock gardens at 10mph.
    Is that low speed or high speed compression?

    That is high speed.
    Low speed is body movements and the like.

    But to confuse you further. High speed impacts still transition through low speed on entry and exit. So low speed compression still has an effect. It's just more minor.

    Thanks, I'm revalving my fork and wanted to make sure I was going the right direction. I'm taking some hsc shims out to soften the hits and the lsc I can adjust with the dial. Feels better with the bounce test will have to ride it and see where I'm at.

    Make sure you retain the original shim spacing with spacers that same thickness as the shims you took out. Some stuff is very particular where the retaining nut ends up.

    What kind of fork? Keep in mind that softening the stack will also affect lsc. Like you said, it can be compensated by changing the lsc adjuster, but soften the stack too much and you can run out of lsc range.

    It's a 2014 rockshox recon 100mm. I updated the compression damper to a Sid rct3 and the rebound is a dual flow from a Sid.
    I did keep the same shim stack thickness. I had some smaller shims that I added on top that will only come into play if the shims deflect a lot. My bike giant anthem 27.5 is light in the front so the fork needs to be much softer. I hope to ride it this Friday.
