Pre-Setup Tips


Installation and Mounting Tips

  • ShockWiz may leave some marks on your fork or shock when mounting. To avoid any scuffs, cut a piece of inner tube to protect contact points.
  • ShockWiz can be mounted in any orientation. Experiment to find one that offers the cleanest routing for the hose and avoid excessive bends or kinks. Make sure no part of your mounting contacts your bike during normal operation or compression.
  • You can attach the hose to either ShockWiz valve. They are angled differently to allow for better routing to your fork or shock valve.
  • Fasten hose connections adequately to ensure a good seal. If ShockWiz later reports unexpected pressure readings, check the connections again.
  • You can reorient the rubber boot if necessary. It's easiest to pull off the boot opposite the side of the valves. To put it back on, insert both valves into the boot first, then pull on the cover.

Connecting to ShockWiz through the App

  • Enable Bluetooth on your phone, but DO NOT use the phone's Bluetooth pairing feature. Connect through the ShockWiz app only.

  • Look for a flashing light on ShockWiz to make sure it is awake. If not, bounce the bike a few times to wake up ShockWiz. ShockWiz will go to sleep if it does not detect movement for 10 mins.

  • Launch the ShockWiz app and use the app's Connect feature to connect to ShockWiz.

  • Expect some delay when connecting to ShockWiz while it identifies the unit and reads any data.

  • The ShockWiz units are labeled as 'FRONT_AFR1XXXX" or "REAR_AFR1XXXX". If you swapped them during mounting, make sure you are connecting to the correct unit or you will be very confused!

Setup and Calibration Tips

  • Remove any 3rd-party modifications to your fork or shock, such as MRP Ramp Control as it is not compatible with the ShockWiz ( Volume spacers and Luftkappe are OK). Check the Compatibility page for more details.
  • ShockWiz may show marginal ambient pressure when your fork or shock are deflated (~1-2 psi). This is normal. Use your shock pump guage reading to dictate what your actual pressure is, so you can repeat the setup later without the ShockWiz.
  • After mounting ShockWiz, start the Calibration procedure from the ShockWiz app. Make sure ShockWiz is ready by looking for the flashing light (note: it only appears on the logo'd side of the device).
  • Infalting/Deflating during calibration: SLOWLY Inflate or Deflate in increments of 10-20 psi at a time. Then fully cycle your fork or shock a few times to equalize the air chambers each time. Most suspension have a point (around the sag point) where you can feel the positive and negative chambers equalize. After each deflation step, extend the fork or shock to full extension. It should be relatively easy to bottom out/fully extend your fork/shock during calibration. If your fork or shock collapses while deflating, you are letting out too much air too fast. Repeat the calibration step at least 2 times to make sure your compression ratio is consistent.
  • Generally, the CR should be in the 2-3 range. The maximum that can be meaured by ShockWiz is 5.0.
  • Once pressurized, note the pressure reading on your pump for repeatabilty later; your pump will likely show a slightly different pressure reading than the ShockWiz app. All pumps will have some variance in accuracy.

Starting a New Tuning Session

  • Connect/Switch between Devices using the Shockwiz App ‘kebab’ menu (i.e. 3 dot menu)
  • Start a new session for each device while OFF/Unweighted from your bike!
  • Always tune in Full Open mode if your fork or shock has a compression lever. Do not switch to Climb mode, etc. while tuning.
  • You can switch to different tuning modes without starting a new session or affecting your score in the current mode. This will show you different suggestions and scores for comparison.

Using ShockWiz

  • Only use ShockWiz in the Full OPEN mode of your fork or shock. Changing the lockout or compression lever will affect ShockWiz readings, which were calibrated in Open mode.
  • Learn how to use the Profiles feature of the ShockWiz app. It will be helpful in recalling your tuning information later. You can learn about this feature in our Setup videos
  • Bring volume spacers and any tools you may need to make adjustments. Of course, bring your shock pump!
  • Make any changes suggested by ShockWiz from top to bottom as displayed in the app. 

    To get the best results from ShockWiz, we recommend tuning in the same order that the suggestions are shown in the app. This is because some changes affect others. Rebound, for example, should follow Air Spring Ramp because a different combination of Baseline Air Pressure and Air Spring Ramp will have a different Rebound requirement.

    Going further, Baseline Air Pressure and Air Spring Ramp are a tuning pair that should be done together. Then Rebound and High Speed Compression should also be done together. Finally, Low Speed Compression and Bottom Out Resistance should be done individually.

    There is an exception to the order. If one of the tuning pairs has a red indicator and the other has green and/or yellow, the one with red should be corrected first.

    If you change the number of spacrs or tokens in your fork or shock, you must re-calibrate the compression ratio within the Shockwiz app. Read more about Tuning Order.
  • For the best results, we recommend that you repeat the same sections of your trail when making changes based on ShockWiz readings. Consider foregoing your normal loop if you need to.
  • IMPORTANT While tuning with ShockWiz, any time a Damping adjustment is made to your suspension, you must select Start New Session to clear all existing ride data.

    Any time Air Spring pressure is changed, you must reset the Baseline Air Pressure in the Settings screen and Start a New Session.

    Any time Air Spring Ramp (spacers/tokens) is changed, you must remeasure the Compression Ratio using the Calibration Wizard.
  • Keep riding until ShockWiz says "ALL GOOD" in the "What to ride next" field.
  • Stuck at 49% Confidence? Ride more of the requested terrain. FYI, “Pedaling (Climbing/Downhill)” means riding on smooth paved roads/trails, like riding to the trailhead. This is not a critical data point and can be ignored if your Tuning Score is >80% as most of MTB riding is not on smooth/flat terrain.  
  • After using ShockWiz and (hopefully) achieving a high tuning/confidence score, it will provide a good baseline for you to tweak from going forward. In the end, it is your preference to dial in your suspension the way you like it to feel and perform and for the terrain you ride.
  • When finished with your session, create a Profile within the app. Connect to the desired Shockwiz unit, then tap the download button (Shockwiz with arrow pointing down), to save your session to the Profile, so you can recall it later.
  • Tip: In the Settings section of the app, there is a SRAM ID link. Creating a SRAM ID will upload any profiles you have created to SRAM servers, so your profiles can be downloaded back to your device in the future. Very handy if you upgrade your phone and want to retrieve your old Profile data.
  • TUNING MODES: There are two modes by default. Choose the one that best fits your tuning goals:

    Balanced – Provides an overall compromise between traction, suppleness and pedaling efficiency. Balanced serves as a great baseline tune and is a favorite with ShockWiz users.

    Playful – Allows for a perfect combination of traction, suppleness, and pedaling efficiency but with a livelier feel to give the bike ‘pop’.

    If the default tunes don't fit your preferences, you can choose the Custom Tune mode. The Custom Tuning Style allows you to select one of fifteen different stiffness and liveliness combination

    Stiffness [Custom Tune] can be tuned with one of five choices ranging from Softest to Firmest. By tweaking the Stiffness, you can alter how much resistance to movement the suspension has. More stiffness will result in a more efficient, but less comfortable ride, which is a XC racer preference. Alternatively, a stiffer Tuning Style could be selected when you are running a bike that is designed for burlier trails (i.e. a 180 mm travel bike on mellow, flowy trails)

    Liveliness [Custom Tune] can be tuned with one of three choices ranging from Planted to Active. By altering the Liveliness, you can change how active the bike feels in ‘dynamic’ (through rough obstacles and on jump take offs and landings) situations.
