@Loamhuck: In regards to tire pressure, or any other aspect of bike set-up (geometry, mass, etc), ShockWiz doesn't know what it is, but it doesn't need to know. It is always analyzing the response of the suspension, looking for undesirable traits and trying to fix them. It doesn't care what induced the undesirable trait (most often caused by the trail, but influenced by the bike and the rider), it just wants to adjust the suspension to get the rider, bike and trail working as well as they can. That doesn't mean that changing tire pressure doesn't have a significant effect on the riding experience - it often does, but these are typically to do with lateral grip and how the bike 'feels' and inspires confidence on the trail - not things that relate directly to suspension performance. Because of tire pressure, the rider may have a different amount of grip / confidence and therefore be faster / slower through certain obstacles resulting in different suspension movements, but ShockWiz will just continue to analyse this and suggest any suspension adjustments it thinks will lead to an improvement.

Hey JC9won4, Tuning a full suspension mountain bike does not require 2 devices. Using one ShockWiz, and swapping it between the front and rear suspension, is no less effective than using two simultaneously. The only disadvantage of using one device is the added time in tuning the fork and shock individually. You are correct about the getting one end of your bike dialed and then moving to the other, and that affecting what you just did. All that means though is moving ShockWiz back to what you tuned first, to see if there are any changes. I wouldn't expect you'd have to tune your fork and shock more than 2 times each before they are very well balance. I would also expect the amount of change on that second pass to be very minimal.

@Sweatypants: Lots of good questions here. ShockWiz does exactly what you're suggesting. ShockWiz offers tuning suggestions for 6 adjustments; Baseline Air Pressure, Air Spring Ramp (Bottemless tokens and bands), Rebound (LSR), HSC, LSC, and Bottom Out Resistance. When suggesting changes to these adjustments, ShockWiz takes a holistic approach. It considers the combination of all the tuning parameters available to us and tries to keep everything in balance so that no force is dominating over another, across all obstacles we encounter in a typical ride. If your spring is too linear, ShockWiz will suggest that you "Add Spacers" to increase Air Spring Ramp. If you aren't using enough of your travel, ShockWiz may suggest a number of things. The most obvious being to "Remove Air" to lower your Baseline Air Pressure. It may also suggest that you "Remove Spacers" to decrease your Air Spring Ramp. Creating a more linear spring curve allowing you to more easily use all your travel. The important thing is that it considers every aspect. The Suspension Tuning Order article is very helpful to determine the correct order adjustments should be made, link below. https://shockwiz.zendesk.com/hc/en-us/articles/229083967-Suspension-Tuning-Order It is important to remember that there is no such thing as a "perfect" tune – unfortunately it does not exist and suspension tuning is always a balance of compromise. A tune that works well on one part of your ride will not necessarily be optimal on a different portion. However, it is possible to get to a point that is a very good compromise between all the aspects we are considering. ShockWiz directs you to the point at which a good compromise is achieved, which we call the ‘Window of Happiness’. As the name suggest, the 'Window of Happiness' is an acceptable range we want to be in. It may consist of 1-2 damping clicks wide and maybe +/-5% Baseline Air Pressure, for any given Tuning Style. It is important to understand that the Window of Happiness is not as simple as focusing on one aspect, such as having your sag at a particular percentage. ShockWiz devices cannot communicate with one another, and you can only connect a single device to the app a time (to view the data). This does not pose a problem when using multiple devices, as all the user calibration vales and ride data is stored on ShockWiz, not within the app. The ShockWiz App is only a means to view the ride data and to interact with the device; such as to calibrate or Start a New Session. Using one ShockWiz, and swapping it between the front and rear suspension, is no less effective than using two simultaneously. The only disadvantage of using one device is the added time in tuning the fork and shock individually. When you are satisfied with the Shock Tuning Score and feel of one suspension component, you would simply move it over to the other.

If they are both air sprung, then yes! Check out the ShockWiz compatibility within our Online Help, link below. https://shockwiz.zendesk.com/hc/en-us/categories/204347088-COMPATIBILITY;

A Salsa Spearfish might be a bit more appropriate. :)

Haha! I probably shouldn't comment of this but couldn't resist, and you're only half right here. Power meters measure the rider's performance, ShockWiz measures your suspension's performance. So based on that, ShockWiz measures how poorly the user has set up their suspension, which in the end is a very easy fix and inherently makes you faster. A few rides, a shock pump and some dial turning and will get your suspension right where it needs to be. Improving your fitness however requires a lot more work and doesn't happen nearly as fast! :)

@MX298: That is more or less correct. ShockWiz consists of a highly accurate pressure sensor and micro processor. The device records the air pressure inside your suspension's positive air chamber while you ride at 100Hz (100x/second). By knowing the Compression Ratio and Baseline Air Pressure of your suspension, the raw pressure values can then be converted to travel percentage. It is the ability to determine displacement that allows ShockWiz to see how your suspension is behaving; how much travel you're using, shaft speeds, etc. It is important to remember that the data gathered is very real. There are really 2 important pieces here; the devices ability to measure and record pressure data at the very high rate that it does, and then the algorithm which takes in the very complex information and outputs very easy to understand tuning Suggestions. The raw data on it's own is of very little use to most.

@frampo: Mike is correct, Fox air springs do not function this way. The Dorado Air system from Manitou is the only air spring that I am aware of that works this way. Basically the air inflation valves on these springs feature a poppet valve that, when a shock pump is installed, opens the positive and negative chambers to one another allowing them to equalize. Once the pump is removed, the valve closes and the chambers become separate again. The ShockWiz hose functions no differently than a pump when installed, which is why it is not compatible. ShockWiz compatibility articles can be found at Quarq.com > Support > ShockWiz Online Help. I also always recommend contacting your suspension's manufacturer or visiting your local bike shop for technical questions such as these.

@dgm10: Thanks for the kind words! A lot of work has gone into this product, it's truly well worth it when we see comments like this. Continue spreading the good word sir!
