A few years ago we tested Shimano's 105 and Dura-Ace mechanical groupsets against each other, and learnt that they were pretty much, in terms of feel, exactly the same. But Shimano has since released new versions of both, and what's more they're both Di2 only! So is there any difference? Is Dura-Ace still virtually exactly the same as 105? Alex and Si conduct a series of tests to find out!
