Fliiiight is shipped aligned for a standard 700c road wheel or 29” MTB wheel. If you have a different wheel size, you may need to adjust the resistance unit up or down. Your magnet array should be level with your wheel rim.
Menu:
Possible symptoms of misalignment:
- The magnets come into contact with wheel or tire.
- The trainer is not able to hit your resistance targets
Required tools
- 4mm Allen key
- 3mm Allen key
Alignment Steps
Two silver mounting bolts attach the load cell to the frame. They can be adjusted using the 4mm Allen key.
Set screws are located inside the load cell, in the two screw holes perpendicular to the mounting bolts. They can be accessed by inserting the 3mm Allen key into the screw holes from the side opposite the mounting bolts.
Height alignment
With the bike installed in the trainer, and the trainer off, slide the resistance unit over to one side, until the magnet array touches the wheel rim. Check that the magnets are level with the rim. Check the other side.
If the magnet array is too low it will partially face the tire. If it is too high it will partially face above the wheel rim.
Align for height:
- Loosen both mounting bolts and raise or lower the resistance unit as needed.
- Re-tighten the mounting bolts.
- Recheck the height.
Alignment for parallelism and concentricity
All Fliiiight trainers are aligned for parallelism and concentricity before shipping, so it's less likely you'll need to do this alignment yourself. You may need to do so if:
- You accidentally alter this alignment while adjusting the height.
- You are mounting a new resistance unit yourself following an upgrade, repair, or warranty replacement.
- The alignment has shifted during shipping.
Steps
Use the same method to check alignment: With the bike installed in the trainer, and the trainer off, slide the resistance unit over to one side, until the magnet array touches the wheel rim.
Concentricity
The magnet array should track the curve of the wheel when viewed from the side. If the front end of the magnet array is higher or lower on the rim than the rear end, it is not concentric.
Concentric
Non-Concentric
Align for concentricity:
- Slightly loosen both mounting bolts.
- Adjust the mounting angle:
- If the front end of the magnet array is lower, tighten the upper mounting bolt until the magnet array comes into alignment.
- If the front end of the magnet array is higher, tighten the lower mounting bolt until the magnet array comes into alignment.
- If a greater change in the mounting angle is necessary:
- Further loosen the opposing mounting bolt.
- Tighten both set screws to lift the load cell slightly further away from the frame.
- Re-tighten the appropriate mounting bolt.
- Ensure both mounting bolts are tight to secure the resistance unit.
- Re-check concentricity and height
Parallelism
The space between the magnet array and your wheel rim should be even from the front end of the magnet array to the back.
Parallel
Non-Parallel
Align for parallelism:
- Slightly loosen both mounting bolts.
- Use a 3mm Allen Key to adjust one of two set screws to change the mounting angle.
- If the magnet arrays skew right towards the front of the bike when viewed from above, tighten the set screw closer to the arm of the frame.
- If the magnet arrays skew left towards the front of the bike when viewed from above, tighten the set screw closer to the bike.
- If you adjust the set screw too far in one direction on your first attempt, resulting in the opposite parallelism error, un-tighten the over tightened set screw slightly before attempting to tighten the other one.
- Re-check Parallelism and Concentricity.
