still under pressure two days later. Is it a really slow leak?? or is there some voodoo at work here?
Bike sat for a week, grabbed it for a ride and the front tire was on the rim.
hmmm
How did you pump it up?JL

If you used CO2, it works for that ride, but you usually need to pump in "normal" air later.

If you used a pump you may have a slow leak. Did you find what caused the original flat? I had some flatting issues a little while back, that was fixed by replacing my rim strip.

Happy riding.

W/the floor pump b/f I left the house. Put my ear on it128

and heard/saw nothing (but did start to pluck the spokes which made a great sound)
Suppose I should replace the tubes anyway...

Thanks and happy riding to you too!

before you replace the tube, check the tire and the rim strip.
Check for slow leak at the valve headAlex-in-Evanston

And if there is a leak there, check to see if your rim tape has some overlap over the sharp edges of the valve hole in the rim.

Pump the tire up to full pressure (or higher) and dunk it in the washtub - you'll see if there's a slow leak by bubble formation. You may need to go around a couple of times (slowly) if it's a really slow leak.
