I repaired one of my bike’s inner tubes last Sunday, which isn’t a tricky thing really, but wasn’t made especially easy by the vague (and dangerously ambiguous) instructions that came with the $2 puncture repair kit. I was a little sceptical that the repair would hold, but thus far it seems to be doing just fine.
So, hooray. Now I just need to fix my other one and I’ll have that as a spare, for the next time – and I’m sure there’ll be one soon – I manage to ride over something spiky.
