    Hi All,

    I’m looking at changing my tyres for better panaracer ones, and while I’m at it thought i would change the inner tubes, having bought the bike last week i hadn’t noticed till now but it seems to have “Presta” type valves and not the Schrader valves (which it states in the specs) as all my pumps (foot and portable) are Schrader types, plus i prefer latter.

    The problem I’m faced with is that the rims are DT-Swiss 445D and look quite slimline and the valve hole only looks large enought for the presta valve

    Can anyone confirm if the Schrader valve tubes fit if they have the same rims or rockhopper pro 2009 or is it just an optical illusion

    I really appreciate any advice

    Cheers

    Pete

    If it says schrader in the specs it should have them fitted. I think you’ll find presta are fitted more to road bikes which have thinner wheels. Is the bike new, or did the previous owner put road wheels on it to save weight ?

    I don’t think schrader valveswill fit in presta holes, and you really don’t want to go drilling holes in a nice set of rims like that.

    Most MTB bike come with presta valves these days, only the lower end of the market seem to come with schrader valves now for example my girlfriends mid range hardrock.

    Why not just buy a couple of presta to schrader valve adapters.

    Sorry Chris I would disagree. I think the shrader valve is just as common.

    I too prefer it due to its robustness and easy to use anyware qualities

    Many MTB wheels can be used for either as they come with an adaptor for when using the Presta (my wifes Mavic 717s)

    My midrange Rockhopper also came with Shrader valves, hardly “the lower end of the market” 👿 😉

    Nah reliable chunky Schrader FTW!!! 😆

    Your just a Roadie Steve 😉

    To be honest all my hand pumps have said adaptor and you can use it to pump up a Presta with a Schrader style (ie car) foot pump.

    I cant be doing with all that undoing the little screw on the top malarky 🙄

    I prefer presta & I’m defo not a roadie!! 😉

    There is arguments for both sides. I like longer valved tubes using presta.

    You mean theose long 3″ jobbies, I have a tube with one of them on that a mate leant me, what is the advantage with them Sean?

    In fact I still dont understand the advantages of the presta apart from size, is there anything I am missing that they do better?

    My old bike, mid-range 08 Rockhopper has Presta, my current SX Trail has presta (DT Swiss rims) even my old Raleigh Max Ogre from about 10 years back had them.

    Can’t think of an advantage, but cant think of a disadvantage either to be honest, certainly not worth being binged £10 plus for anyway.

    So, let’s conclude:-

    Presta for the sportier cyclist who knows where it’s at.

    Schrader for the tuggos!! (Marty and Harry will know what this means)

    😆 😆 😆

    Steve,

    I am not sure what that means 😆 the only reference I can find is a 1970 article about Ron Cooper opening his shop in Forest Hill

    “Ideas on building have changed during his 23 years (he started work seriously at the age of 15), but he has kept pace with the times, making frames for tuggos and top riders, wide boys and world champions”

    So I asume its not good! 😉

    At best is it a type of “Domestique” rider at worse is it a proper w*nker 😆

    alot of the longer presta ones are for road wheels, and alot of them have deep section rims etc…

    and much more bikes are coming with high pressure valves now…

    More the former but certainly not the latter! 😉 😀

    In my day, this was also interpreted as someone of limited knowledge and ability who uses the art of moving himself up in a bunch sprint by yanking his position further up the field with the help of his hands and other rider’s jerseys!

    So, kinda low-key version of Sean Kelly, really!! 😉 😀

    In practical terms, you can use Presta valves on rims drilled for both but Schrader … ? Need I say more! I currently have Presta tubes in my Kona (Schrader-drilled) rims and any of my frame-fit pumps always had Presta-fit ends.

    FWIW, in the old days (here we go again 😕 ), there were high pressure valves (Presta) and low pressure ones for utility bikes (Woods valves, where you had to unscrew a metal bit halfway down the valve.)

    I therefore believe that Schrader is the newest of the three.

    Nah, not that long. Not sure why I prefer them, I just do. They seem a bit better engineered to me. The screw on collar helps when changing tyres/tubes. I tend to be light on parts and not break or rapidly wear stuff. If I rode a bit harder and was a bit more heavy handed I may prefer the chunkier valve.
