Dura Ace 7900 Shifting Problem?
I just picked up my bike last week, newly built up with DA 7900. I took it out for a test spin and found that I could not shift from small ring to big ring. When I tried to shift, the chain would go around the big ring, but when I released the lever, the chain went back to the small ring. I tried SEVERAL times, no success, then chain just would not stay on the big ring.
I called my mechanic and he said 7900 is a little different and just to shift a little harder. I have very small hands and can't shift any harder than I already am. In order to shift from small to big ring, I literally had to reach over with my right hand and yank the lever hard - then the chain stayed on the big ring.
I'm so disappointed that I have not taken my bike out again. Anybody else have this issue? I never had this problem with 7800.
