Shimano XT instead of 105
I've contacted Sheldon Brown for advice. Asking him for replacements for my 105. He told me that 105 is nothing special, and his personal choice would be XT.
Thus, his personal choice would be mountain bike der for your road bike. Why?
Is XT better than 105, Ultegra, Dura Ace? I got the sense off him that it is stronger and shifts faster, but isn't lighter, but who cares. What are you thoughts on this one?
