Don't expect it too much, you get what you pay for
It's just another ordinary cheap tube, nothing more.
Thick, not light, but quite OK for the spare or daily
Had 2 flats within a month, but that even happens to
another tubes like Conti's or Michelin's or whatever.
A puncture is a gift from the wicked angel telling you
"Have a break" and you've just got to simper and say
to her " Thanks for caring about my health, not my
bloody training schedule ! "
I'd be furious if it was 4 times more expensive like
the ordinary tubes, but then again, I only have to buy
4 of these. It pays me even if this was 4 times weaker.
Don't expect it too much, then you'll be OK.
Say hello to the wicked angel if you ever see her.
