We've got a loan of a shockwiz and planning to use it across 4 or 5 bikes.
Given the model of fork is it possible to find a document with reference of the compression ratio and load that into the app therefore avoiding the calibration step? The app or videos we've seen hint that it's possible to directly enter the CR but the details are sparse.
Any Shockwiz experts on here?
Unsure, but you may be able to do it with the initial setup for the bike and then save it...then create a new profile for Bike 2 and repeat...however, I don't know if that is possible. I have 1 Shockwiz and 1 bike so I don't tend to save the settings.
I wouldn't think a reference table exists, you have to recalibrate it if you add tokens. You can add the compression if you know it.
Shout if you find reference values.
Yes you can just enter the compression ratio if you already know it, and skip the calibration.
I can't remember the exact option but it's obvious when you look at the app.
The calibration takes 3-4 mins. It's hardly worth worrying about
Theoretically possible but given the number of variables between fork model, travel and tokens I’d just run through the calibration. Like nuking from orbit, it’s the only way to be sure.
It's really difficult with some forks/shocks to hold them at full compression/extension for the calibration. I don't remember how I did my Pike in the end but I remember trying all manner of things including ratchet straps and having the bike sideways across the hallway with my back against one wall and my feet on the handlebars so I could use my legs.

I have always found it better to put a little air in if I’m having this problem. So long as you can easily hold full compression and extension you will get the ratio calibration without necessarily having zero pressure. Otherwise you may get a ‘bullworker’ style workout 😀
If you know the ratio you can enter it manually but remember it changes based on number of tokens - ie it's worth doing the calibration the first time you set it up.
Tip I discovered the other week is to really slowly let the air out - if the forks suck down more than 10-15% you’ve gone too fast. Apparently doing it slowly allows both positive and negative chambers to equalize when depressuring, preventing the suck down problem.
Thanks all, I misinterpreted "enter the compression ratio if you know it" as read it from a manual rather than enter CR if you've used shockwiz before.
Tuning underway!
@bearGrease what forks are you setting up?
I'm frankly amazed that there isn't a resource with compression ratios out there somewhere. Even SRAM/Quarq haven't bothered!

So was I, especially for RockShox products.
I guess there's no incentive for anyone to do it. Perhaps a minimal one for RockShox perhaps if they're doing the ecosystem of complementary products thing.
It would be too large a table to be useful as there is so much variety in setup options.
The setup steps really don't add much time or effort. Very easy to get full compression and assuming you have a strong grip with legs, then grab wheel between legs and push down with feet on tyre, then pull the bars up - full extension can be achieved without much sweat.
Same setup for rear shock...
Once set up you can save profiles and re upload them so that in theory you could swop between firms without all the measuring again

Not really, a simple excel spreadsheet would be easy to set up; it's only 6 options per fork for each travel setting. It just needs someone with the time and inclination to do it. Before anyone suggests I do it, I'll have the figures for a Fox 38 170mm and Zeb 180mm travel soon.
