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?

We have 1 of those adapters, he dropped it in the grass in the dark last night. I never thought about leaving them on the valves. But in the dark that would not have helped much. I am getting him to order a presta pump.

You might consider adding a small tool kit to the list. I've seen a couple that Velcro under the seat, that way tools and adapters are always available when he's riding.
