I have been having an inordinate number of flats from thorns and glass
on my 29'er. As I was fixing one today I remembered a little gizmo that
I used to have on my road bike. The thing was called a tire saver, and
it was basically a wire that rubbed gently on the tire. It would knock
the stuff out of the tire before it had a chance to do any harm. I made
one for my 29'er, and I'm sure it will save me from patching so many
flats in the future. Unfortunately it won't work on anything knobby,
just smoothish road tires.

I used a wire coat hanger, and made a yoke that attaches with my brake
bolt. Two small pieces of plastic tubing connect the yoke to the wire
that rubs the tire (another piece of coat hanger). I bent the wire on
the tire to the profile of my tire, and the light pressure from the
plastic tubing is all that holds it against the tire.

I may make it a little narrower so that it can go under the fork crown
and be tucked out of the way, but for now it should work nicely.
