As mountain bikers, Presta valves are something we just deal with. However, it's strange how many other things we have optimized, such as headsets, seat posts, drivetrains, wheels, and even shoes.

Today we'll discuss the kinds of valves cyclists have used over the years, why mountain bikers ended up with Presta, and how new options have become available, like premium, tubeless Schrader, and Clik.
