bad luck on the puncture
i had skoda emergency 'slime' in my car front tyre for over a year with no problems and its easier to use than string kits. you just take the valve core out pour the stuff in put core back in and pump tyre up.
i have a string kit on the bike at all times but never used it so cant comment on that but have seen vids of how to use them and it looks like a faf. i also have a core remover valve cap on the rear wheel as i have had cores come loose.
since i know how good the 'slime' is i'm thinking of changing over to one of those on the bike, its an emergency repair so its only to get home.
