I've been on a GUB 1159 saddle for a couple years now with great results. I've been looking to get another to replace the old saddle on my 29+ winter bike. I've been happiest with a saddle width between 135 and 140. I happen to come across this on Amazon the other day. I have not ordered one yet so I have no experience with it. But other than the white logos on the top, it looks like a great option at a very low price. The rails are definitely carbon and the listed weight would suggest that the rest of it is as well. Just wanted to share if anyone else is looking.
