Dura Ace STI defective?
I have a brand new pair of ST-7800 Dura Ace shifters still in the box.
I was examining the left shifter lever. When I push in on the brake lever which would shift the front up to big chainring, the lever only moves about 1 inch at the end of the lever and the mechanism makes one click sound. When I push on the inner lever nothing much seems to happen. I can't believe that small of a movement is going to be enough to shift the front derailleur. Is this lever defective or am I missing something? Thanks - Joel |

False alarm - I wan't pushing on the inner lever hard enough to release
the mechanism. Now the brake lever rotates in about 2 inches. |

Is this lever defective or am I missing something? I suggest trading for some Shimano bar-end shifters. -- Tom Sherman - Fox River Valley (For a bit?) |

Thanks - Joel Probably when you install the lever and inner wire all will be OK, Make sure the shifter is in the 'small ring' position before you install the cable!!!", The spring of the front der will show it's probably OK. All lever mounted shifters, with all the springs and doo-dads in them can feel a little wierd not on a bicycle. |
