The tubeless rim tape is extremely user friendly and at the same time very high pressure resistant. Even on road bikes a single ply of tape is sufficient.
Only use wheels that have been specifically approved by the manufacturer for Tubeless conversion. Especially with the high-pressure demands on race bikes this is very important. Only the wheel maker’s approval ensures that the rim is up to the particular stresses in operation and the tubeless tire will be secure.
