I thought perhaps when I hit a bump the nipple might have move in towards the tube and punctured it. There wasn't any damage to the liner inside the wheel but I thought it may have pushed in enough to pop the tube.
spokes cause flats all the time
but not 20 inch gashes
flats caused by spokes are usually small holes
or sometimes even a spot that seems to be worn through
threadbare almost
for a long gash to open up
the tube must be unrestrained by the tire
unless it was a small hole caused by the spoke
and it was ripped into a long tear by rough removal
but that is kind of unlikely too
you'd have to almost do it deliberately
