Evening guys,
After riding my Lyric with only LSC and LSR for over a year and totally happy with it, I recently bought a Ripley with Fox Float 34 Factory. As you know, it has both low and high speed compression and rebound.
I thought it would be nice to have at the very least HSC on the Lyric since Ive grown to like this on my Fox 34 fork.
I see Rockshox offers an upgrade for both the air spring and the damper that would give me HSC. Does anyone have thoughts on Rockshox oem upgrades for the nice damper or is there an aftermarket company that offers the same for my Lyric that eill give me HSC?

THANKS a ton in advance guys.

IMO no point. The RC and RC2 are only different with the HSC preloader and preloaded stacks IMO feel terrible. Ride the RC and start playing with shims if you feel the need.

Dougal, thank you for the help. Forgive me if I ask a rookie question here.

I believe you need to go through LSC before you get to the HSC circuit. If there is no adjustment to the preload HSC circuit by way of a knob, then are you saying just go in and start messing with the shim stack itself? Wouldn't be easier to have access to the stack and its preload with a knob from the outside?
What is it that you are saying feels terrible? The stock RC with no HSC?

No completely sure I know how it works.

I agree with Dougal, I swapped an RC2 top unit for RC recently when rebuilding a Charger damper.

Here is a very simplified explanation;

For the main compression circuit; oil can either go through a hole in the middle of the piston, or though ports in the body of the piston which have a stack of shims on top of them. They both "work" at the same time.

With the RC2 version, there is a spacer backed by a spring that adds pressure to the shim stack on top of the piston. This is what the HSC knob pushes on. It is limiting in that you cannot modify the stock shim configuration (which is only 3 shims) that much without introducing even more preload which is generally harsh. Shims are springs themselves, by preloading them you can get that terrible feeling.

With the RC version, you can modify the shim stack to your hearts content without introducing preload as there is nothing limiting shim stack height. There is no other force pushing down on them. Tuning via shim stacks allows for huge variations. Go down the rabbit hole a bit.

The LSC knob (on both versions) pushes a needle into the hole in the middle of the piston to control how much oil can bypass the shim stack.

HSC and LSC can both be controlled via the shim stack itself and how much flow you allow it to see.

The RC is what comes on the select models of the forks right? Didn’t know you could crack open those dampers for custom tunes

Basically the best ride you're ever going to get is with the right shim stacks and no HSC preload. So the knob is counter productive in that respect. Stock it has a soft compression shim stack and adding preload to it by the adjuster makes it feel worse.

Yes sir, the RC is just a Charger 2.1 damper without the HSC adjustment. Everything else is the same.

It's too bad SRAM doesn't sell it by itself. It is the best damper configuration they offer IMO. Very easy to work on and tune.

In the RC2 2.1 compression damper, does HSC open = zero preload?

Is there any benefit to running HSC Open or even removing the preload spring, while adding some shims for support?

Yes it's clear. You can see it here: http://instagr.am/p/BucXcMJFiWz/

Ahhh, I gotcha now. Thanks for your help Dougal. I might just mess around with the stack during these winter months, if not for anything else but to learn.

Have a good holiday.

I don’t think it is. The select+ damper is a 2.1 with only lsc adjustment. The select damper (RC) is a spring backed IFP, different from the 2.1

I think that's right, forgot about select and select+.

Charger 2.1 RC Select+ is the winner.

I have the Lyrik Select with RC, and am going to upgrade the air spring in it before anything else. I'll report back when I get it done and have a chance to ride a bit.

Does anyone know. If it’s possible or if anywhere sells reconfigured shim stacks for the lyrik or even sell the information on what shim stack configuration would be an upgrade?

Very good question. Interested myself
