I think the tube size is variable, i.e. fit for different sizes.
The rear tube on mine was a lot bigger than the tyre and was suitable for the standard and larger tyre.

If the tube is'nt clearly marked for a 130 replace it. Best buy an Avon to suit the tyre, surely the supplier of the tyre should stock the tube?
Steer clear of nondescript tubes, there is a lot of crap about. I see it most days

cheers for that stumpy.....forgot you have distanzias fitted so i take it you utilized existing tubes then ?

Plus get a named heavy duty tube, for piece of mind. I replaced my rear tube with the tyre the front was fairly new, will change next time if the rust around the valve stem is risky.
