This is an updated version of my previous inner tube deflation tool. I added threading to work with Presta tubes. This tool is handy while doing bike repairs when you need to deflate a tube to remove a tire, reposition the stem, etc. The Schrader end is particularly useful for me after I've patched a tube. It makes it easy to roll up the tube. The Presta is less so but still handy from time to time.
No support needed.
