Which inner tubes do I need to buy? Evans cycles informs me they have "Standard presta valve".

So looking on wiggle do I want these

or these
http://www.wiggle.co.uk/continental-qua ... nner-tube/

And what type do I need?
Presta 42mm 650x18-25 Race 26
Presta 42mm 700x18-25 Race 28
Presta 42mm 700x25-35 Cross 28
Presta 42mm 700x28-37 Tour 28 SL
Presta 42mm 700x32-47 Tour 28

Don't want to ride and then have a long walk home. I'm guessing I should have a practice at swapping the tubes at home before risking it all out there...in the wild.

    Thanks. Out of interest, how did you find that out?

    presta - type of valve
    42mm - length of valve
    700 - diameter of wheel (700c etc)
    18-25 - diameter of tyre (23c 25c etc)
    Race - Marketing BS
    28 - no idea...

    Spesh tubes are the most common, but personally I can't abid them 'cos I always break the valves

    But that may just be my pumping technique :oops:
    It's just a hill. Get over it.

    Inches.

    Race 28 is yer standard middling inner tube for 28" AKA 700c wheels and tyres. The name indicates weight, with heavy to light: Tour > Race > Race Light > Supersonic.

    I found the valve on Specialized's standard tubes (32mm) to be too short for my track pump and RS10 rims. I like Schwalbe, though I'm sure Conti are fine too.

    Getting the hang of wheel & tyre removal and refit at home when relaxed in is a very good idea.
    Aspire not to have more, but to be more.

    Ah ok cool. Thanks all. So the same inner tubes should fit on my girlie's specialized globe vienna 2.

    Cheers all.
