Fitting the right size inner tube
Hi there, I have just started to commute to work. Rather I should say I attempted to, got a puncture after the first 5 miles which I couldn't fix and had to call for rescue.
To preven this happening again I am replacing my cheap and chearful tyres with some Specialized All Condition Armidillo Elite's (700x23c) at the same time I purchased a new set of inner tubes Specialized 700x20/28. However when I have come to fit the inner tubes they seem bigger than wheel rim.
When I emailed the seller they told me they where the right ones.
So basically what I wanted to know if this is actually the case, as I don't want to fit them and then get stranded half way into my 11 mile commute.
