Presta vs Shrader

Use the one that fits your rim hole. Thats all you need to worry about

Why worry so much? Just flip the valve insert in most modern pumps and you'll have your Presta/Schrader switch. :wink:

Yes but we put an end to the Presta vs Shrader debate, with our dual tube invention :D Run one of each tube in the same rim :shock:


Hey, bicyclewa - has anyone every told you that you think too much :)

Went to the servo...Max. that the pump will do is 60psi (not good for presta valves - besides you'll need an adaptor)

My work compressor (used for drills, nail guns and rattle guns) has a guage that goes to 160psi. Never fired it up to pump a tyre though...too
noisy.

As for Presta vs Shrader: I've heard that shrader valves can not handle the higher pressures over long periods and will gradually leak...which ultimately means a flat over time.

My Europa is wearing a pair of thornproof tubes I fitted in the eighties ... with Schraeder valves. I pump her tyres to 110 lbs. They don't leak appreciably.

Of course, I might have the two that prove the rule :roll:

There's a lot of misinformation about both. Bad Schraeder valves will leak, but so will bad Presta.

I heard of a bloke screwing that wee nut right off the top of a Presta valve and having the pin fall into the tube when he pressed it with his finger - doesn't mean you don't use Presta, it means you don't be an idiot when handling them.

Let those who worry about such things get upset about them. Me? I use what's on my bike unless standardising makes sense.

I normally think a lot when I'm riding. I can't think straight at the moment. It's 42 degrees and I just took the PC out of the freezer :shock:

It was 12.7 degrees when I rode to work this morning. My nuts have mostly defrosted now...

Rub it in. We're in for another day of over 42 degrees. It's 30 degrees at the moment. I just put my other PC (server) in the freezer so it will start. It's a specially designed wafer computer and it doesn't like heat, so I have to freeze it to get it to start.

Might put myself in the freezer next.............. :shock:

So I was just walking to my Uni Law Tutorial (I actually do Commerce :P ) and just as i say bye to my mate he replies "oh wait, i got something for you" I think you can imagine the bemused "what the..." expression that crossed my face. Pulls a Topeak Pocket Rocket DX mini-pump out of his bag accompanied by a simple "Happy Birthday"... :shock: i guess that sorted out my pump search :D and man did i thank him! But it also makes me wonder, how much do i talk without realising...the guy isnt even interested in cycling, and he bought the pump i had been seriously considering... :? gotta watch myself, it seems i have a big mouth :D
