Presta Valves?!

Can someone please explain to me the advantage of Presta Valves over Shraders? It seems to me that they are just a pain if you want to use additional puncture protection (slime etc) but I really can't see any advantage too them.

Why different valve lengths too?? :?:

Thanks.

    different valve lengths for deeper rims

    but I also believe because the lock they maintain higher pressures - the downside is the pins are very prone to shearing with out a flexing connector

    I've never sheared a connector - you'd have to be pretty clumsy to do that.

    One advantage of them is that they will fit in a rim made for schraeders - so if you only carry one type of tube - carry the presta.

    So shrader valves won't fit on a rim designed for prestas?

    That's a pain if true because I was planning on changing the tubes to sharder valves when I get my new bke. I still can only see that prestas are a pain in the rear, no performance advantage over shraders and less versatile to boot.

    Nope Schrader valves are too wide to fit through a presta hole.

    You wouldnt want to drill a hole bigger than necessary through a narrow road wheel rim.

    Thats the advantage - the rims are stronger like that. By all means drill your rims out if you want to - but whats the advantage ?
