FCK Flats Installation Guide:

  • 2) Cut FCK Flats® to size and join with provided velcro
  • 3) Install one side of the tyre bead, then install FCK Flats® into the tyre
  • 4) Remove the valve core from your tubeless valve
  • 5) Install the second bead, being careful not to over stretch the tyre
  • 6) Re-fit valve core and inflate tyre to seat both beads
  • 7) Once seated, deflate tyre and remove valve core
  • 8) Press the tyre down to ensure FCK Flats® is flat and sitting evenly on the rim (see note)
  • 9) Squirt tubeless sealant in through the valve stem and refit the valve core
  • 10) Inflate tyre and spin the wheel to check the tyre is running straight, if not, deflate and repeat step 8.

Please note: If the FCK Flats® is not sitting correctly then work the tyre until it sits flat. It is very important the FCK Flats® is sitting flat and evenly inside the tyre.
