[Closed] Shockwiz Compatibality help

Dual Position Pike isn't compatible but Solo Air is as far as I know. Don't see why the DBAir Inline wouldn't be compatible either?

Now I see, the newer parallel valve just doesn't leave enough room to fit the Shockwiz to the DBAir Inline

I take it dual position means adjustable travel? Yeah that makes sense, reckon there could be a way around it with an adapter or something?

Thanks for the reply.

You want one of these to fit the shockwiz on a Cane Creek IL air.

I'm not sure that is going to work. It would help to have a valve adaptor to clear the can but that Topeak device is a check valve.

Shockwiz is a great little device. If things aren't compatible, it's for one of two reasons. Either something has more than one air chamber, like dual air rockshox or mrp forks, or because it mechanically doesn't fit, like on some of the cane creek rear shocks.

Would this possibly be better suited then?

Thanks again!

(Assuming it fits in the Cane Creek valve and doesn't have the original issue..)

"I’m not sure that is going to work. It would help to have a valve adaptor to clear the can but that Topeak device is a check valve."

It works spot on. I would not have recommended it if I had not used it!

Well that’s great news as I ordered one last night!  Thanks for the tip!

@Rick Draper - can you help me with the theory then please?

I'd imagine that as the shock compresses, the internal pressure increases and is registered in the shockwiz. As it extends, the pressure drops, the check valve closes and the pressure in the shockwiz is then higher than the pressure in the shock body.

I've not tried it experimentally, I'm just working through it theoretically.

Cheers guys I'll give it a go then. Think the fork should be fine and hopefully the adapter will allow me to do the shock too.

Actually thinking about this I can see where Onzadog is coming from - if the ShockWiz relies on measurement of pressure changes in the air spring then I can see why a one way valve would mess this up.

The shockwiz manual talks about simply removing the valve core in its entirety, where for example the valve pin is too deep to be depressed by the centre pin of the shockwiz hose.  So I’m guessing the gubbins of the check valve could also be removed if push came to shove.

I suspect the Topeak extension is not a one way valve.  When they say check valve they mean it can be connected and disconnected without losing any air from the shock.  Whilst connected air can flow in both directions

If you read the instructions for the pressure rite, it's a standard check valve.

I don't think it is a check valve (i.e. internal thing you can't control); the pump end has a regular Schrader valve that will be depressed by the ShockWiz, and the business end has a pin that will push on the valve of the suspension bit to be tuned. Air will flow freely into and out of the ShockWiz.

If that's the case, wouldn't the shock valve be held open and the air escapes when the shock pump is removed?

I have a pressure rite. You can blow through from one end, but not the other.

"If that’s the case, wouldn’t the shock valve be held open and the air escapes when the shock pump is removed?"

Its just like a valve extender, it depresses the valve core as the shockwiz hose does, its not a one way valve of any sort. You just make sure you undo the adapter from the shock not the adapter from the shockwiz hose.

I wonder if yours might be stuck open.

I now have visions of Onzadog blowing furiously through his pressure rite 😂

Can the valve core be removed from this thing?  If push comes to shove that’s what I’ll try, though I guess you’d need to remove the core from the shock body too...

Nope, you can't get into the check valve. I've had to send one back under warranty a few years ago as it stopped checking but there was nothing that could be done.

Doesn't take much of a pressure differential to activate the check valve.

B**ger - off to Halfords for a normal extension then!

Onzadog is right, one way valve. I thought what a crap idea, how do you bleed a little air if you've put a little too much in and the answer is Topeak make a version with a bleed valve.

B***ox - got home and realised I have a dbair cs, not an in-line, so the dam thing fits after all!!!! ☺️

Problem solved then! Let us know how you get on. Got a few weeks to wait for mine.
