The width of the rim tape should be in line with the rim recess. If it is too wide it will tend to come off the rim, but if it is too narrow it will not ensure a perfect seal.
In all cases, it is preferable to choose a rim tape that is approximately 2 mm wider than the width between the rim hooks.
When using tape, we recommend two inner turns, with a minimum thickness of 0.1 mm. This gives a good guarantee of reliability and durability.
