You will need a Garmin bike computer to see the FORMA data in real time. Currently, the FORMA is compatible with 530, 540, 830, 840, 1030, and 1040 models. FORMA data is also logged in the Streamlines Nimbus app, and this logging does not require a Garmin bike computer.
Please note the FORMA requires a USB-A to USB-C cable to charge. It will not charge when using a USB-C to USB-C cable. This only applies to the FORMA sensor, and not to other Streamlines devices.
ALIGNMENT
FORMA CIQ
FORMA DF
To use your FORMA sensor with a Garmin bike computer, we recommend installing both the FORMA CIQ app for the initial setup and the FORMA DF datafield for use while cycling. Both are available on the Garmin ConnectIQ store.
The FORMA CIQ app provides a simple environment for the setting of the target position while the FORMA DF allows body positioning data to be easily displayed within a user’s existing activity screens.
Our recommended path for the installation of the Garmin-FORMA software is through the use of both ConnectIQ and Connect mobile apps. ConnectIQ downloads the FORMA software onto the mobile and Connect installs the FORMA software onto the bike computer.
For further information on ConnectIQ Apps and Data Fields, please see - Understanding the differences between Garmin Apps and Data Fields.
When a FORMA DF data field is added to an activity, the body position data will be automatically recorded within the FIT file and displayable within Garmin Connect.
A Garmin Connect IQ app creates a separate activity environment outside of the user's existing activity environments, such as Road or Indoor. In contrast, a Garmin Connect IQ Data Field allows additional data to be displayed within an existing activity environment, such as Road or Indoor.
The only information shared between FORMA CIQ and FORMA DF is the target position, as this is stored on the FORMA device. All other connections and display information are not shared.
For the best FORMA performance, position the bike mount midway along the stem. You can install a standard Garmin ¾ turn mount on the stem, or the handlebars, or a custom mount when using aero extensions. For assistance with custom mounts please send a message to support@streamlines.aero
On stem, using Garmin 1/4 turn mount system
With the FORMA sensor now connected, navigate to Main Menu > FORMA Settings > Set Reference Position.
You can set a reference body position by A) measuring and recording new values or, B) using known values from a previous test:
A) Measured Values - To measure and record body position place bike on a stationary trainer (or have someone hold the bike) where the rider can maintain their correct body position. Body position measurements can be recorded by pressing the 'Measure' button and holding the desired position for 5 seconds. Loose fitting clothes can interfere with measurements and give inconsistent results. It is best to wear tight-fitting garments for this step. If you are happy with the measurements press 'Save' to record them, otherwise re-measure.
B) Known Values - Body position measurements can be entered manually by using the +/- buttons.
After setting the Reference Head and Chest Positions, press 'Save' to record the values.
The tolerance band around the reference position is called 'target zone'. The smaller the target zone, the stricter the position feedback will be.
The default value is +/-1.5cm, but it can be manually adjusted to your personal preference. Go to Activity Profiles > Road > Data Screens > Screen 1 > Connect IQ Data Fields > FORMA DF > Display Settings > Graphics > Target Zone. Input desired values and press 'Save'.
The FORMA DF data field shows body position data in visual format via the two arcs and moving white dots. The right arc corresponds to Chest and the left corresponds to Head data (these are displayed for 30 seconds when you enter the screen).
Red means Head and/or Chest are above the target zone. Blue means Head and/or Chest are bellow target zone. Green means Head and/or Chest are within target zone.
The target zone is displayed in +/- cm, and is determined by the target zone measurements. Instructions on adjusting this value are outlined on page 17. Under the Display Graphics menu you can hide the target zone measurements and display rider power instead.
You are now ready to ride with your FORMA sensor. Please read the 'Important Safety and Product Information' section (page 21-24) before proceeding.
To connect a different FORMA device to the one previously connected you must first clear the existing connection.
Go to FORMA DF Settings > Connect IQ > Edit DF Settings? (yes) > FORMA Connection > Clear Current Device? (yes).
Now you can follow the on-screen instructions to connect a different device.
Body position data is stored in the FORMA unit. If connecting to another Garmin device these will be carried over. However, settings such as Target Zone size and other graphic options are stored on the Garmin device itself and therefore will not be carried over.
If the FORMA device becomes unresponsive you can manually reset it by inserting a pin into the hole above the charging port and pressing it down for 3 seconds. This reset only cuts off the power and will not erase any stored data.
Please periodically check if your FORMA sensor is running the latest software version by downloading the Streamlines Firmware Updater App (available at the iOS App Store and Google Play Store) and updating it when appropriate.
How to use the Firmware Updater App:
The Garmin Connect software should update automatically.
However, if the Garmin app has not updated, check the ConnectIQ mobile app to see if there is an update queued. Garmin hardware sometimes needs a restart to load a new version.
BICYCLE WARNINGS:
WARNING:
Failure to follow there safety and product instructions
could result in damage to the FORMA device. Please read all the information below before using your FORMA.

The FORMA device uses a class 2 laser. Class 2 lasers are considered safe for normal operation. Class 2 lasers are relatively weak and would not harm an eye unless a person deliberately stared into the beam. Protective eyewear is not normally necessary. However, a Class 2 laser can be a distraction, glare, or flash blindness hazard for pilots and drivers. NEVER AIM ANY LASER TOWARDS AN AIRCRAFT OR VEHICLE THAT IS IN MOTION. ONLY ALLOW USE BY RESPONSIBLE PERSONS.
Exposure to Radio Frequency. This device is a portable transmitter and receiver that uses an internal antenna to send and receive low levels of radio frequency (RF) energy for data communications. The FORMA device has been tested and emits RF energy below the applicable limits for portable radio frequency (RF) exposure use when operating in its maximum output mode. To comply with RF exposure limit requirements, the device should be used as described in this guide. The FORMA should not be modified or used in other configurations.
