• Was cleaning the bike the other day and found the front mudguard was filled with dirt bound together with latex. Clearly the front tyre has had multiple punctures and sprayed out latex sealant but never enough to cause a significant loss of air.

    The front tyre is cut to shreds, a couple of weeks ago it had a cut that kept opening and closing for half a day, but it has sealed back up and remained stable subsequently. If it were a normal tyre I'd have binned it by now just from appearances - but it seems to have loads of life left.
