I've had 6 in the last two weeks. The only thing I can think that these tiny pieces of wire came from is a destroyed truck tire. Which I've seen many of.
You can't see these little bits in the tire until its too late. Running a glove hand over the tire does nothing to dislodge them or even tell you that your tire is doomed.
Anyone have any ideas how to prevent this?
My Roubaix is sitting on the stand right now with two flats. I have to fix tires again before I can ride tonight.
