The OEM tires are supposed to have puncture resistance, but I decided to have the LBS put on Gatorskins--glad I did.
Yesterday I rode the new bike on my normal route. At the bottom of a hill was broken glass--like from a broken beer bottle or two. There was no way to avoid the hazard unless I had seen it far earlier and had slammed on the brakes. The bike and tires didn't skip a beat. I tried to avoid what I could, but I definitely went through a glass minefield. I checked the tires thoroughly and found maybe one tiny splinter that I plucked out, but the tires looked great. I didn't see cuts or anything. I checked this morning and the inflation hasn't diminished.
