I just discovered that the shell of my Toupe has broken all the way through at the thinnest part. This seat does have 11,000 miles, but I wouldn't consider this something to happen as normal wear and tear, and I only weigh 140 lbs. Has this happened to anyone else? As I understand, Specialized equipment has a limited lifetime warranty. Should I even bother with a warranty claim on this? Just curious what you'd do.
