I was sitting there, messing around on the computer, when Pow! Psssst! and the front tire on my bike became flatter than a pancake!
I had, just before the 30 mile ride yesterday, put a brand new tire and good tube on the wheel! Now it was flat and it was clear that nice solid inner tube had a good sided hole in it!
How did this happen????
So I did.
With the tube out, it wasn't hard to find the hole:
That is one big hole!
Not good, not good at all!
Hole on inside... must be either:
Part of the strip had gotten roll on top.
The picture shows the rim side with the spoke hole clearly shown.
The one on the left was the spoke hole that caused the tube hole.
The good news is that I had gotten replacement rim strips a while ago...
The bad news is that I should have replaced the old ones when I changed the tires
since the it was several years old and getting brittle (as I can tell now).
