Well I got my 3rd and 4th flats with the Hemisphere Armadillos. I'm disgusted right now.
I have put thousands of miles on $14.00 Tioga city slickers with out a single flat and these $30.00 skins have had 4 flats in the last month or so. I was actually able to identify the reason for the 3rd flat... a small piece of beer bottle glass went right through the tread and pierced the tube. I think that the reason for this is the tread itself. The nimbus armadillo on the front has never flatted.
Specialized is getting a call on these tomorrow.
I did get in 50 miles today. Nice riding against a heck of a wind FIRST and then get pushed for 25 miles.
