Ive ordered one now from Amazon. One to stick in the bag and hope its not needed. Will be blowing it up before putting it in the bag to make sure it works
Well, the one I ordered..a 28"...arrived today...
It must be big enough to fit a 32" wheel if one exists!
Going to contact the seller tomorrow...it just doesn't look right to me. I blew it up a bit to make sure no leaks, and then compared it next to my wheel....there must be 4 inches extra tube. I guess you could just stuff the lot in the tyre before blowing it up just to get you home, but just seems wrong....
Incidentally, it wasn't boxed like shown in the pic, and has no size markings on it at all....
