Hi all, basically, is there any advantage for one over the other? My wheels will only take presta but am thinking of drilling it out to take Schrader, good idea or not?

    Bad. Take what ever your rims come as.

    Thinner rims need a thinner valve which is why you do not see any with schraeder valves.

    You can drill them out but you may compromise the strength.

    But as you do not mention what you have who knows.

    Just had a few probs with the screw on pump removing the inner valve when removing it, thought I could eliminate this. I'll just leave it as it is I think. Cheers. Chris

    Biggest problem with presta is that the world has accepted Schrader.

    I prefer Schrader as I have an electronic pump in my car but right now after a puncture, currently sporting presta in the rear and schrader at the front and will do so till the next puncture as I paid £7 as it was an emergency!!

    You can get adapters for presta to accept Schrader pumps...about £1 on ebay and come in anodized colours for extra bling.

    Absolute rubbish.
    Every road bike has Presta, plenty of MTBs have them, and any BICYCLE pump costing more than 99p fits both.

    Stick with Presta. They're slightly easier to hand pump

    My lbs told me that the presta has better pressure retention. Don't suppose that matters for an mtb because you are changing the pressiure far more often than a road bike. The issue is drilling into your bike or your wheel. I would never consider drilling a hole in my bike frame (eg to lose water from the BB) equally I would never drill my wheel rim. I cannot articulate the risk but I believe there is one and I won't take it.

    It depends on the width, build and what material is there. One thing's for sure it'll never be stronger.

    Easy to articulate - the rim will collapse, you will crash and die.
    No harm done.

    That's the other thing - easier to quickly let a bit of air out with presta valves. This matters if you ride on the road to where you're going to ride off-road

    Just asking as my forks/shock/car hold air fairly well.

    Heh. Your shock is nothing pressure wise. They can take several thousand psi easily.

    Schrader valves

    I think you can get ones up to ~3000psi. This is from a forum thread (on here I think) a while back so I may be wrong.

    So you are arguing with the wrong person.

    What? I didn't think I was arguing with anyone. It was meant to be more like additional info or something.

    In retrospect I should have said "And shocks are nothing pressure wise" rather than adding the your. Or added smiley faces. They are always good :)

    By a quick calc that would be about120kgs on a schrader valve - pi*r**2*3000 convert to kilos. That would be marginal!

    The Schrader valve we use is one of a family of valves, no way will it do 3000psi, but others will, do a google image search.

    Doesn't really matter if the valve can take 3000psi or 3,000,000psi, what really matters is if they can keep 30 to 40psi. If a schrader fits you can fit one, if not you'll have to fit a presta. There is really no point in compromising your rim. If you have to fit presta and want to use a compressor, you'll also need a small adapter.

    This is the most sense I have read in this thread!
