I just recabled with the Dura-Ace cables. My bike came with (at least they looked like) in-line barrel adjusters. After taking them off and looking at them I can't see how they could possibly adjust anything...almost looked like a barrel adjuster case with no moving parts inside.
Anyways...do they make in-line adjusters with some sort of indicator that allows you to see the position of the cable? I have no mounts for typical adjusters for the down-tube, so I need to score some in-line adjusters.
