I have an eye toward building a commuter/grocery-getter from one of these frames. Similar in their features, with eyelets I'd need for a rear rack and possibly fenders, and both have vertical dropouts. The ES has a shorter wheelbase and steeper seat tube, while the Double Cross has a notably longer top tube and 4mm (66 vs 70) less BB drop.

Opinions? The bike won't be doubling as a tourer. I'll probably put some kind of flat bar on it and build it up with 1x7 or possibly 2x7 gearing.
