@grzesiek355624: musi-nie musi, presta to nowa pompka, może drugie nowe koło, więcej wydatków niż to warte. Jeśli casual, to obręcz na dowierceniu o milimetr nie straci zauważalnie wytrzymałości, zwłaszcza jeśli i tak była projektowana pod AV.

@cucaracha: presta jest starsza niż schrader o kilka - kilkanaście lat

However, based on the other incidents around that time, it is speculated that the first ever Presta valve supposedly came into existence in a year somewhere in between 1880 and 1890.

The Schrader Valve is also called American Valve. It was invented in 1891 by August Schrader. The original design of this valve was patented in 1893 in United States
