Here's what I consider a big drawback of EPS - that battery is rather fat and chunky. And unlike the Shimano battery, which can rather easily be replaced by a hidden seatpost battery, the Campy battery has integrated electronic chips, meaning it's a bit of a black box that's harder to hack. In any event, that battery looks kindof ugly in that spot right there, which was originally designed for a Di2 battery.
Our second day on the Interbike showroom floor was another great harvest of gear photos and new info. Today we looked at a variety of things, from Campagnolo EPS all the way down to a simple BTA bottle from Profile Design. There's plenty of great stuff in the gallery - have a look, and check back in tomorrow for our final gallery.
