I had Ruby out for 55 miles on Saturday. Around mile 53, cruising a nice downhill something started clicking loud. I was just about stopped when the tire popped like a .357. I was about 1.5 miles from a Specialized shop and just walked the bike to it.
The LBS, Aspen Creek Cycles, my new heros, said it was the second tire that day. Seems to be a lamination problem. the tire had less than 700 miles on it. They hooked my up with a comparable tire, free tube and labor and said that Specialized would pick up the tab. WOW! Blew me away.
I was back on the road in 15 minutes of entering the shop.
Keep an eye on your tires if you have Specialized Roubaix. I'm trying my first century next Saturday. I feel "blessed" that the tire blew Saturday last and not Saturday next.
