Love the bars! They are On One Midge. I have been using them on my main road bike for over a year. I ported them over to the touring bike and have just ordered another Midge for my road bike. I went with a white bar in 31.8 to better suit that bike's equipment and color scheme.
By Swallow I take it you mean my Brooks. It's actually a "butchered" B-17. It's nice but I like my Selle AnAntomica much more.
