Tubeless Ready Wheels
Advantage 1 - Lighter: Since no tubeless tape wrapping on the Tubeless Ready wheels, the weight of the wheel goes lighter than the weight of common wheel with tape wrapped;
Advantage 2 - Stronger: No holes drilling on rim bed (except valve holes) and the carbon fibers not being damaged, the rim bed would be kept integral and the strength increases;
Advantage 3 - Safe: Tubeless Ready wheels no risk of air leaking from the rim bed, the cycling stays safe and the journey could be longer than riding bike with common wheels.
Disadvantage: Needs professional maintaince in case of spoke breaking
Note: Tubeless Ready wheels could also be mounted with tubes.
