Fit App

Version 4.1.1

May 11, 2026

App Updates - 4.1.1

This update is a fast follow up to a Pedal Spindle Offset bug that affected some users after 4.1.0.

Pedal Spindle Offset Recommendations

PSO is directly affected by setup technique. Follow these guidelines for successful captures:

  • There needs to be clear line-of-sight to the Vantage for foot, heel, wrist, and hip markers.

  • Minimize upper-body motion during pedaling. The Vantage uses the wrist and hip marker to determine what side it is looking at. Motion blur caused by movement will affect PSO. If the Vantage doesn’t know what side it is capturing, it will not work.

  • Ensure that the hip and wrist markers have good horizontal separation. This means the rider is perpendicular to the vantage.

iPadOS 26

October 15, 2025

There have been recent bug reports relating to the iPadOS 26 update.

The bug is affecting the zin data from not updating when loading a zin into the spreadsheet display. To workaround this, once you have loaded a zin, leave the screen by tapping on assessment or pose in the slider, and then return. The display should then update to the zin that you have selected.

***We recommend that fitters do not update their iPad to iPadOS 26 due to these bugs.***

If you have already updated your iPad, rest assured that our team is focusing on resolving the bugs that have appeared.

If you have already updated and are experiencing an issue, please report that as soon as possible through the App Feedback button.

Once an app update is available, this page will be updated.

If you are a Fit App user and have not been receiving the App Update Newsletters, please email bodygeometry@specialized.com. These newsletters are sent from iContact.

This has been resolved and updating to iPadOS 26 is no longer a concern.

  • After hitting “Complete Fit and Send Report” Fit status still shows as “In Progress”

  • After Zinning a bike in the app, if you feel that the bike hasn’t been auto-leveled by the app, re-zin the wheels and trace as much as possible. This applies to all bike types except when using the MUVE SL.

  • Pedal Spindle Offset

    • We are aware that users are continuing to experience issues with the Pedal Spindle Offset feature in the Fit App.

  • Hardware times out after no activity

    • Sacral Sensor (AnGi) goes to sleep quickly.

      • The app cannot wake up the AnGi on its own. When you are ready to conduct a pose capture, tap or shape the device to wake it up. You will know it is awake once you see the green light flashing.

      • Make sure you have removed the thin plastic slip so the battery makes contact with the device.

    • Zin Wand

      • If the Zin Wand is not used after connecting to the app after a long period of time, the tool will disconnect.

  • Issue when loading Pose Capture into the “Rider View”

    • When in Pose captures under the ”Rider” view and you go to load the right side the capture will always display double or with a high degree of error.

      • One work around that some fitters have found success with is to unload the capture and reload it.

  • Unable to Generate Personalized Ranges

    • Even after completing Dynamic Movements Steps, the app is unable to generate personalized ranges.

  • Client Creation: Date of Birth 

    • When you are entering the birth date for a new client, start with the birth year and then you can update the month and date. 

Additional Tips and Tricks

  • Updates: Email App

    • Some fitters have reported that when they try to email a rider their fit report the email does not send from the iPad. Here are some tips to help with this:

      • Log out of the mail app and log back in.

    • We do not recommend using your personal email on the iPad being used for fits. This will avoid accidentally sending a fit report from your personal email and avoid other shop employees from seeing your personal emails.

  • Pedal Spindle Offset

    • We are aware that a number of fitters are unable to find the left or right pedal spindle when conducting a fit. Here are a few tips for working around this or other data points you can use. These recommendations come from our SU team:

      • Pause and restart the session after the first side is finished.  After you restart it the "second" side now measures normally.

      • Knee forward of spindle as a way to quantify saddle setback.

      • Bi-lateral data to determine saddle shape and width along with any other bilateral issue we might see in the assessment.

      • If you cannot get both left and right Pedal Spindle, you can substitute with Knee forward of foot. This requires the you to create a new Pose group that includes that metric.

  • Unable to Generate Personalized Ranges

    • Even after completing Dynamic Movements Steps, the app is unable to generate personalized ranges.

    • We are aware that a number of fitters are unable to find the left or right pedal spindle when conducting a fit. Here are a few tips for working around this or other data points you can use. These recommendations come from our SU team:

      • Pause and restart the session after the first side is finished.  After you restart it the "second" side now measures normally.

      • Bi-lateral data to determine saddle shape and width along with any other bilateral issue we might see in the assessment.

Version 3.0.6

August 30, 2024

Release Date: Jul 2, 2024

Current Known Issues

These are issues our team is aware of and we are working on getting a fix out as soon as possible!

  • Pedal Spindle Offset

    • We are aware that a number of fitters are unable to find the left or right pedal spindle when conducting a fit. Here are a few tips for working around this or other data points you can use. These recommendations come from our SU team:

      • ***NEW: pause and restart the session after the first side is finished.  After you restart it the "second" side now measures normally.

      • Knee forward of spindle as a way to quantify saddle setback.

      • Bi-lateral data to determine saddle shape and width along with any other bilateral issue we might see in the assessment.

      • If you cannot get both left and right Pedal Spindle, you can substitute with Knee forward of foot. This requires the you to create a new Pose group that includes that metric.

  • Zin Data - Last Client Data Loading

    • We are aware that some users are experiencing an issue in the Zin Module. Users are reporting that when loading “Initial” and “Latest” Zin, data from the last fit client is loading rather than data from the current client.

    • If you experience this issue, pause your fit and then return to the fit. This should load the correct client data.

    • If you are experiencing this issue or if this workaround does not work for you please let us know via the feedback button.

  • Assessments showing as “SKIPPED” in reports.

    • We are aware of an issue where assessments that are completed for a client will show up as “SKIPPED” in the report.

  • Unable to Generate Personalized Ranges

    • Even after completing Dynamic Movements Steps, the app is unable to generate personalized ranges.

  • App is slow to respond when searching for a client

    • When searching for a past client, you may experience slowness when trying to type a client name or the app may be slow to generate the results. Here are some suggestions if you run into this behavior

      • Be patient and allow for the app to catch up with your actions.

      • Organize your clients alphabetically and scroll until you find the client you are looking for.

  • Client Creation: Date of Birth 

    • When you are entering the birth date for a new client, start with the birth year and then you can update the month and date.
