2 saddles on 2 different bikes, both have the exact same wear patterns with thousands (I'm guessing 7500-10000 each) of miles on them. No tearing or seperation but I am slowly wearing through the leather and it shows discoloration. I have more of a knees in pedaling style, so instead of wear marks on my cranks, I get them on the saddles. One has even bounced off the road a couple times on both sides, chaffing but that's it. Pleased with the quality but they will need replaced pretty soon I'm sure.
