Shimano Ultegra Di2: First ride on the electronic groupset

Shimano Ultegra Di2

As a quick recap, the key difference between the ‘Ui2' and Di2 is cabling - a two core, not quad core wire is used. While that renders the two incompatible, it does benefit the overall look as the Ultegra level cabling and connectors are noticeably slimmer.

Ui2 doesn't have the carbon and titanium paraphernalia (some of which was tucked away out of sight in Di2 anyway) but that doesn't really affect the overall aesthetic, which is practically identical. Even the alloy brake levers look like their more expensive uni-directional carbon brethren.
