As you should know, years ago tubeless technology arrived to the MTB world, with the promise to make the quality of the wheels better eliminating punctures. Still the weight and the high prices of tires have stopped the introduction of it in our sport. Besides you should has experienced with TUBELESS it’s also possible to have a punctures! As a result, the tubeless system has won a bad reputation and the majority of bikers still keep using tires+inner tubes in their machines.
Ride without inner tube will be for sure much better. The rest of vehicles we know work with no problem with this system for a long time. The fact is bikes are different to the rest: A bike is the lightest vehicle compared with the cargo weight that rides over very hard terrains at a very slow speed… and has a human traction. Tires must support all types of abuses and must be built as much lighter as possible. That was not easy to achieve.
