IIRC presta valves are designed for higher pressures and shrader aren't.
I use shrader on the MTB but I don't run massive high pressures, usually around 35psi depending on tyres/conditions.
Can't really see it makes too much difference but my mate said if you're ever out with a puncture and your pump is shot, you could blow it up at a garage with a shrader valve
presta is a good one to have as a spare, as it will always fit through a hole in the rim, (for your schrader running mate who forgot an inner tube) (being narrower than Schrader). possibly an argument for a stronger rim with smaller diameter holes (though I am perfectly willing to be mocked at this suggestion!)

I've had this – pump exploded and died miles from home. Garage airline did the job. Although nowadays many UK garages have those stupid push button machines which probably aren't so good for this as the old whooshy tube machines.
Absolutely true about air suspension using Shrader – not sure if the pressure thing is only applicable to tyres, I read about it somewhere when I was thinking the same as the OP. Could be a load of pony though.
One thing I do like with presta is the nut that screws down against the rim which helps as it stops the valve pushing downwards when you're trying to get a pump on.
Drill 'em out! I've done it to loads of rims, Mavic, DT etc. No problems at all. As for the 'strength' argument, if you saw the tiny shavings of alloy removed by enlarging the hole, you'd realise it's not valid. 😀

Schwalbe inner tubes have these on the schrader tubes too.
schraedar on the MTBs – Presta always seem fragile to me, add mud into the equation and my chances of killing a perfectly good tube are increased dramatically
Presta on the road – anything else would just seem wrong
use a frame fit pump on the road, so no issues with sharing pumps
I reckon its down to rim width, narrow rims as used on road bikes would be less stressed with smaller hole. so they use presta.
It doesn’t matter for mountain bike rim widths so either will work, but Schrader is a better more reliable valve. (You wouldn’t use presta on a car would you?)
It's not normally a choice I find it has more to do with the size of the hole in the rim…
If I had to choose, Schrader I can whack the compressor on it without an adapter, works well enough for cars, presta valves are too delicate, and offere no advantage so far as I can tell…
anything, my bikes are a right mismatch and continuously changing, only 3 rims won't take either and there may even be a woods valve tube kicking around in something
both valves seem to do the job
keep meaning to standardise, but it only takes a minute to turn the pump insides around
bigyinn –
presta, as they are easier to deflate than schraeder ones.
ay? use a cap with the integral removal tool and your tyre is instantly deflated!
anyway, schraders are used is loads of industrial applications, high pressure schraders are good for 2100 psi, even the cheapos used in pneumatic tyres are good for 210 psi.
i stand to be corrected but as far as i know prestas are only used in cycling and came about due to the smaller diameter of the valve body.
