I gotta give Fizik credit. Basically the entire original Kurve product line was defective (given enough time the shell would start to crack, regardless of rider weight). Knowing this, Fizik revised the line for 2015 and is offering free replacements. All I had to do was fill out a warranty form and attach a couple photos of the cracking. They shipped me a new 2015 model direct from Italy free of charge. No proof of purchase, no questions asked.

Definitely the most comfortable saddle I've ever ridden, but too spendy to put on my commuter bikes.
