I purchased this saddle last year to replace a broken one on a second-hand road bike. I needed something relatively inexpensive (and in a hurry), and was able to get one for a great price at the time. Weight wasn't really a deciding factor.
As others have pointed out, don't expect any sort of comfort from this saddle. I rode mostly 40+ mile training rides on it, and ended up using it for the annual Seattle To Portland road event (~204 miles).
It's a good seat for most occasions, but I don't recommend it for long rides. Docking a star because shorts with padding are a must, unless you have a leather bum. Ergonomics could be a little better as well, even with the minimalist padding built into the saddle.
