What are the benefits of presta over Schrader valves? (slrpnk.net)

My son recently got a really nice specialized bike used. It came with presta tubes on it, and a few extras. Last night he called me in the middle of the night to come pick him up because he had a flat and he could not get the pumps on campus to work with his tubes.

He said he could have probably ridden home on the low tire, but he was trying to fill it up but instead the pump kept releasing more and more air.

I personally see no benefit to presta valves, but there has to be some... right?

You have some options. First, you could just thread these adapters onto the presta valve(after opening the presta valve stem cap) and use a schrader-style pump, that's your cheapest option but I've come across a very few schrader pumps that don't work with this. They were unable to pass air to the tube. Tell him to be sure to close the presta valve after filling.

If he carries a backpack or has a free bottle cage mount on his bike, , he can carry a compact pump , they often will work with either valve. Full disclosure that it can take quite a few pumps to get the tire to the proper pressure.
