Schraeder vs Presta Valves
 

OK, I've always used tubes with Schraeder valves up until a couple of years ago, when I put new tires on my MTB; decided to give Prestas a try. Yes, I used grommets on the rims in the stem holes. I've now had my 4th leaky valve stem since using Presta valves. The first two I could have accepted as being my fault, since I could have possibly not mounted the tube perfectly on the rim. But the last two were put on by a bike shop. Sunday morning we drove to a local green way and were going to take a ride, then I found my rear tube was leaking.

I'm going back to Schraeder. Has anyone else had issues with Presta?

Which ones are which? You talking about the ancient ones, like what cars use, or the newer ones with a skinny little thing in the middle?

If you don't know the difference between the two, you obviously have nothing to add to this thread. :lol

I know the difference between the two, seeing as how I have 2 bikes with both of them, but I forgot which name applies to which. But if you're going to force me to do a Google search instead of answering my question, so be it.

Do you realize you could have Googled it and gotten the answer in much shorter time than it took you to reply? :?:

Do you realize you could have answered my question in less time than you spent on your two pseudo-replies thus far?

My neighbor has those Presta Valves on his MTB

He's ALWAYS complaining about them.....I can't see the benefit personally....but I'm not one to ride a umteen thousand dollar MTB.

Irony is he's too cheap to buy the $40 pump to air them up himself...so when he has to air up, we have to swing by the bike shop before the trails :td:

So, just did a Google search, and yes, the Prestas are over-rated. They are too sensitive and don't seem to hold air as long. The only advantage is they seem easier to pump, because of less resistance I guess.

Of course I do. But why should I? Lazy mother fucker.

I haven't noticed any difference in the amount of time to pump them vs. te Schraeders on my wife's bike (same pump - it has connections for both valve types).

Glad to hear it's not just me having problems with them.
