I never tried this was a bicycle but did do it with a motorcycle gas tank
with reasonable results. Fill the top tube with water, plug the ends and
leave it outside to freeze. The expanding water may push out the dent.
The water will also likely cause rust in the top tube. You may need to
put some frame saver in the top tube before you do this. I am not certain
if the frame saver would lower the freezing temperature of the water. I
believe, worst-case, the solution would not work. Best case, it is an
inexpensive way to repair a dent. Better do it soon because outside
temperatures are rising. Good luck.
