Ok I fixed the puncture(well replaced the tube) so now I need to buy a new spare tube. I went here:


and got confused. :tongue:

I tried googleing the name of the old tube but got nowhere.

My tyres are schwalbe marathons

On the old inner tube I see these numbers:

on the tube box it says 700 x 35c & 700 x 38c Presta

....I know this is a simple thing but it's all new to me..so apologies....I just want to make sure I dont get stuck out on th eroadside in a thunderstorm with a flat and the wrong spare inner tube :?:

Many thanks :biggrin:

28x15/8x11/4 & 700x35 or 37
are old fashioned ways to describe a 622x 35 or 37 tyre.

a tube marked as any of the above, would fit all the above.

silly, i know..you can read all about it here
