Hey Yeti
Yup, I've got an 08 Elle. We are in love
What would you like to know? I can go on for hours about how comfortable her plush geometry is and how beautifully smooth the ride. Oh, and don't go and get me started on the build.

In the process of picking her I also test rode a Diva. I think it all depends on what your wife will be doing with the bike. If she wants a 100% race machine, maybe the Diva is for her. It is definitely a different feel to the Diva's carbon. And the Diva geometry is set up to let her be as low and fast as possible. The Elle is setup to be a more comfortable bike (check headtube length etc) and she will sit up a little higher on the same size frame. However, I find my Elle to be so so comfortable that I can go for hours. Given that I'm not a racer I think in the long run I'm just as fast on my Elle simply because its easier on my body. Does that help?
