First look: New Shimano 105 road groupset

Shimano has unveiled a new version of its mid-level 105 road groupset which features plenty of trickle-down technology from the company's higher-end groups. According to Mark Greshon of UK distributor Madison, the new 5700 series 105 is "designed for riders looking for all the technological features of Dura-Ace and Ultegra at an unrivalled price".
