Dozen ish rides old. On the side wall, just enough for a tiny bleb of tube to poke out. Anything worth doing to repair or just sack it off and stump up for a new one.

Dental floss to stitch carcass back together then big tough patch on inside will see it right, no point ditching it if fixable!

Gotta be worth at least attempting to fix before you buy a new one! Above method is the standard way.

Nice one. Not heard the dental floss remedy before, every day a school day and all that. Cheers fellas.
