The inner tube adds additional weight and imbalance to the wheel of your bike, that combined with the gyroscopic effect increases the perceived weight when you make changes of direction at medium and high speeds.
How much weight do you eliminate with the Bartubeless system?
The Bartubeless system removes the inner tube from the wheel and applies a special lighter polymer to seal its channel.
This difference in weight, which apparently seems small, actually becomes big if we consider the masses in motion. In fact, when the wheels rotate, they put the masses in motion and the faster they rotate, the more this weight increases. If we put together lower weight, better pressure distribution, better balance, and better print on the ground (which is determined by the pressure distributed better) at the same speed we will have a huge benefit.
