Checking for Clearance

NOTICE

Failure to perform one or more of the following actions could result in possible property damage.

NOTICE

When attaching the thru axle or quick release axle, you must check for clearance using the compatibility gauge (installation kit A symbol). Interference between the bike and the Tacx® Alpine could result in possible property damage (Installing the Tacx Alpine).

  • Ensure no objects obstruct the power cables.
  • Route the power cables so that they will not interfere with the trainer or the Tacx Alpine during use.
  • Check for clearance around the bike chain stay and bike fork in all height positions and while turning the handlebars.
  • Get on the bike, and ride in manual mode (Going for a Ride).

    The AUTO LED is off.

  • Ensure there is adequate ceiling height while riding.
  • If necessary, go to the Tacx Training app, and set grade limits.

Checking the Chain Stay Clearance

Before you perform this clearance check, you must set the correct bike wheelbase and trainer in the Tacx Training app.
TIP: You can use the measuring tape included in the installation kit A symbol.
  1. Press Arrow up symbolArrow down symbol at the same time to return the Tacx Alpine to 0% grade.
  2. Observe the smallest distance between the trainer and chain stay.
  3. Open installation kit A symbol, and select the compatibility gauge 1.

    You should be able to fit the gauge between the trainer and the chain stay.

  4. Press Arrow down symbol, checking the clearance each time you press the button.

    You can also control the grade manually using the Tacx Training app in the device settings.

  5. Repeat step 4 while monitoring the clearance between the trainer and chain stay:

    • If at any time the gauge cannot fit between the two parts, go to step 6.

    • If the two parts are clear from 0% to -10% grade, go to the next clearance task (Checking the Bike Fork Clearance).

  6. Press Arrow up symbol, and note the grade.
    TIP: The Tacx Training app displays the grade.
  7. In the Tacx Training app, go to the Tacx Alpine settings.
  8. Select Grade > Grade Range.
  9. Use the slider to set the minimum grade.

Checking the Bike Fork Clearance

You will need the compatibility gauge from installation kit A symbol.

  1. Press Arrow down symbol until the Tacx Alpine is in the lowest position.
    NOTE: The minimum grade is either -10% or a custom value (Checking the Chain Stay Clearance).
  2. Rotate the handlebar as far as possible (in both directions and on both sides), and insert the gauge between the fork and the Tacx Alpine.

    If the gauge fits between the two parts, in both directions, no further action is required. If the clearance check fails, continue to step 3.

  3. Open installation kit A symbol, and select the protective strips.
    TIP: Garmin® recommends cleaning your bike fork before placing the protective strips.
  4. Place the protective strips on your bike fork where the bike fork is closest to the Tacx Alpine.
