Measurement & setup app instructions

Updated 30/1/22

Please see the following page for instructions on how to assemble your tool.

The application allows you to save multiple bike profiles, then use these as a reference when measuring/setting up a bike. The application has 4 tab pages <Profiles> <Saddle> <Bars> & <Hands>

<Profiles> allows you to manage your bike profiles, including a backup/restore function. The other tabs all work in a similar way, displaying the target profile data on the right hand side, and your active measurements on the left. Values in grey boxes are calculated for you, although all “Active” measurements can also be input manually. This is useful if you want to manually input or modify a profile.

There is a “Measure angle” switch at the top of the Saddle and Bars page to turn on real time angle measurements and calculations. Use this when the phone is in the device and turn the switch off to lock the measurements.

You can update/replace the profile data with the active values on the current tab by pressing the “Save Active to Profile” button.

The backup/restore function can be used to simply copy/paste your data into another application e.g. an email. You can then use this to restore your data, or copy it to another device.

The “Share” button allows you to share a particular bike profile with someone else. This uses your devices share feature to create a link that you can send to someone else (or another device) that when opened will open the app and give the user the opportunity to import the profile.


My recommended way to use the tool is to first define a reference profile, either based on your bike fit data, or by measuring your reference bike. Then “duplicate” this to create additional profiles for each bike you have, because in reality there is likely to be a few small differences between each. You can then capture and store the measurements for each one separately.

See the following pages for details on each step of capturing your measurements

For bike fit professionals and other advanced users there is also an “Advanced Mode” that enables some more complex features that have been requested. This includes indicating when the position is not UCI compliant and some additional visibility into the devices orientation to help align the tool more accurately. UCI measurements flagged are saddle set back and bottom bracket height.
