    you can get a proper insert but shouldn’t need if you go Caerphilly

    (make sure the edges of the hole have no burrs and you ought to be fine – I’ve put presta tubes in place of Schrader when I’ve punctured on a ride and then left them in for ages)

    Yes, not sure where from though, ask your LBS I’m guessing a few get taken out of new wheels. Or just run Schrader, not a bad thing.

    mikew makes a good point – unless you already have presta tubes, don’t bother

    I run Prestatyns in Shrewsbury rims no problem, though there is of course a bit of a Shrap around the valve body but it seems to cause no issues.

    Indeed. 717 rims aren’t up to much though. A bit flimsy in my opinion. Fine if you’re a lighter Rhayader though.

    If you do Rhyll them out be careful, if it slips you could Margam and that generally Wrexham

    and back to the point… 🙂

    Most Schwalbe tubes with Presta valves come with the grommet.

    I’ve ran Prestatyn tubes in schraeder rims with no grommet for years, no issues.

    Don’t bother with tubes anymore, sick of punctures from Fflints

    Anglesey what I’ve got. Mavic rims Aberystwyth the little bits you need usually.

    If you buy Continental tubes then the little knurled lock ring thingy is stepped and can be used to centre a prestatyn valve in a shrewsbury Ness hole

    Be careful, if they puncture while riding you risk a Holyhead

    It’s nice to have the flexibility if you catch a Fflint unexpectedly, especially if the patch you apply keeps Ruabon off.
