Of course they do, But a week later and it's totally flat and the OP can not find bubbles in water just means he wants us to pup his tube up.
I have a better idea, Let him swap the tube and see what happens after a few weeks.
I said a couple of weeks and it is flat, not a week and it is flat...and actually this time it was probably 4 or 5 weeks, lord knows when it was actually flat. I pumped it up last night and just came back from a 30 mile ride and it is still fine. The REAL problem is that with a presta valve it is hard to CHECK the air pressure without letting some air out....and if ya let air out, how accurate is the check?
If I rode this bike more often I would most likely never know it leaked because i generally air up my tires every other day.
For all I know, my other geared bike might do the same thing.
I don't understand how you interpreted this as me wanting YOU to pump my tube up.
When I pumped it up last night and examined it in the water I had it blown up to the point where it was like4 feet in DIAMETER..LOL....... is that stretched enough?
Never mind guys, if I have to pull this out again, I am pitching it and replacing it. My time is worth way more than a new 4 dollar tube!
I just thought I might be missing something
