I have this saddle on my single speed commuter bike. It's great for riders who who racing saddles on their road bikes. It's not as narrow as a typical racing saddle, but it is narrower than the B17.
In terms of break in, the saddle was comfortable right out of the the box. This is in comparison to my racing saddle, which is rock hard. This saddle is not hard, but it is not cushiony either. If you want something more cushiony, a Brooks will take some time to soften. That being said, after a month or so of riding, it has started to feel more broken in.
It was easy to install and adjust, but that is more a reflection of the seat post and clamp. However it is a standard two rail saddle.
I would certainly recommend this to a roadie who also wants a hipster commuter bike.
