What are the main changes in the Dura Ace line between 7900 and 9000. Is it just 10 speed to 11 or was there performance changes. Beyond weight.
7900 was the first year that Shimano went to the buried shift cables(running under the bar tape and along the handle-bar). The shifting was OK, but felt dead. They have been able to refine this with further year upgrades and make it better.
I have a mix of Dura Ace 7900 and 7800(shifters) on my road bike. The 7800 shifters were the last with the exposed shift cable out front. It looks a little old-school even vintage, now, but when tuned up, shifts like a dream - very crisp and accurate - actually better than the 7900 that came after!
