OK what a challenge! So I got out the dictionary.

Unruly comes from reuly or easy to govern or reule to rule. I guess it is an English adaptation of the French word.

Unkempt comes from kempt to comb.

Disgruntled comes from gruntled to complain.

and non-plussed comes from plused, plusing, pluses, plussed, plussing or plusses which means to think, say or do.

So yes, some can be ruly, kempt, gruntled and plused. So what's your point? Guess I'm gruntled!

I am a Presta guy on both my roadie and my MTB. Why, you say? They have less air resistance due to their smaller diameter! Besides, you think Lance uses Schrader-equipped tubes?

A survey of 25 MTB rims available at Jensen USA (certainly not a statistically ballanced survey) showed 9 of 25 rims to have Schrader valve holes..............7 of those from Alex Rims ( a notorious provider of low end rims to the stars). Those providing presta..........Mavic, Surly, DT Swiss, Salsac Velocity Aeroheads and most of the Sun/Sun Ringle.

It is more likely that high end MTB's come with presta's because high end Rim manufacturers use them than other reasons.

This in no way determines the reasons or rightness of why these rim manufacturers choose to do this. It could be as simple as "tradition".

Edit: Then it is hard to explain that my Mavic Crossrides (low entry point high end rim...) came drilled for Schrader but with and insert to neck them down to Presta. The insert thing is nice because it provides a nice smooth bushing with no burs or sharp edges for the stem.

His point, and I have to give him some credibility as he has been a LBS owner for 25+ years, has been highly successful in building a small chain of stores and is a high volume dealer for several major brands, is that these wheel manufacturers had to switch to presta in order to sell their high end wheels. That cyclists wanted the "European" look of prestas on their wheels instead of the more pedestrian schrader valves. He said that he has received that same comments hundreds of times and it was almost never because the buyer liked the functionality of presta, but they wanted the styling.

Note this was from mountain bike buyers. Although he added that with modern materials, one doesn't need the smaller hole of the presta even on road bike wheels, however it would be a waste of time to try to sell them unless a popular Tour de France cyclist would use schrader.

Maybe I still haven't got the hang of it.
You are not losing air out of the tire. The hiss you hear is air escaping from the pump hose.

The only advantage that I can think of that schrader valves have over presta is that you can pump the tires up at a gas station without an adapter.

I have bikes with both.

I work in a bike shop as a mechanic althought I'm not a bike geek. I'm a car nut, a Harley guy, and an aviation enthusiast and pilot. I've worked as an auto mechanic and have restored cars, motorcycles, and airplanes. I love working on bicycles because they're silly simple. The people I work with a great but it seems the only thing on their radar is cycling and bicycles. The presta valve is the silliest POS I know of. The only advantage I can see is they go through a smaller hole which I'm told doesn't compromise the strength of narrow bicycle wheels. Nobody has ever given a good reason as to why they're better than a Schrader.

Wow ... talk about thread resurrection!

I believe I read long ago that the advantages of presta valves were:

1. When inflating, you aren't having to apply the extra pressure to overcome the spring pressure to open the valve.
2. They have a smaller diameter, and hence do not compromise rim strength as substantially.
3. They are easier to deflate completely, so you can flatly fold a used tube up.

Another advantage:

They sound Italian. That's generally a good thing on anything bike related.

I switched to Presta valve tubes for the simple reason that I was ALWAYS LOSING THOSE STUPID CAPS every time I inflated a schrader tube. I got tired of searching for them incessantly, so I use prestas, and throw away the useless caps for those.

An untightened presta valve is also a fascinating cat toy, evidently. "slap, hsss, jump, stare, approach, SLAPSLAP, hsss..."

Edit: I just realized that I typed "caps" in caps! Unintended typographical pun!

This resurrection gives me a chance to ask a question concerning Presta valves. Are they known to be available on tubes other than 700C road tubes?

The reason I asked is that I recently assisted a gentleman passing through on a Sun recumbent trike, complete with trailer, plenty of gear and spare parts. It appears to have been the Sun Tad 20/26. He had a pinch flat on a front tire/tube. He carried two spare tubs for the fronts (20" as I understand), but we were both surprised to see that these spare tubes (that he hadn't previously inspected) to have Presta valves. I feel fortunate to have stopped to assist because his only pump was for schrader valves, and I carry a small frame pump that will fit either/both.

Thanks......

Sure - tubes for folders and recumbents in 16" and 20", tubes for MTBs in 26", all available in presta, probably even your choice of stem length. I'm surprised your guy had 20" tubes and didn't know they were presta though... definitely not the standard, so unlikely you'd get them off the shelf at the LBS by accident.

Another Schrader problem: I had a Schrader valve get hot and leak on a long descent on my tandem - somehow the spring check just got hot and deformed or something. Made the strangest whining sound and then I had a flat. Can't happen with presta.
