Forgot my saddle wedge, so of course I got a flat coming back from my turnaround point for today. Walked about 1.5 miles to the Redmond Trek store where I got a new tube and pumped it up fine. Got about 5 miles before the new tube blew, too. Another 4.5 miles of walking brought me home

Lucky I was wearing my Sidi touring shoes and not cleats; as it is, I ended up with a blister on my heel.

Second flat - I'm walking home from here:



Crap



Inside of casing:



I was not amused when I got home and discovered the failure - both times - was apparently weak casing at one of the tread features.

This was one of those Michelin Dynamic Classics. Never an issue before. I'll be keeping an eye on the others for awhile...
