i tried that as well on the second tube and it still did the same thing
i even bounced the wheel and it bounced pretty good but when i got
on it and rode around it looked a little flat again. after trying two tubes
that have been used before i decided to get a new tube this morning
also the first tube on the wheel was pumped up by an LBS. my friend and
i drove in his van to the LBS to have them tighten my cog and lockring and
they decided to pump the tire too but after we drove home the tire was
completely flat. this was the tube that was on my previous wheel. i checked
everything and found nothing wrong. not even with the tube. after that i
decided to go on to tube #2. still didnt pump up right. bought tube #3 and
still having the same issue. this is so lame. i just want to ride.
