I believe I have seen Presta on some higher levels of some Mountain bikes before. Personally I think Presta is easier,


If you ever need to uses a Strader pump they have theses things, I keep on with all my bikes and in my back pack just in case. You can pick them up at any bike shop.

Do if your afraid of Presta witch I was kind of at first, all you need is an adapter, I now have even seen plastic adapters come with cheap pumps before.
