hey all,

I've read up on sheldonbrown, and the park tool website, but I've either misdiagnosed the issue, or fixed it incorrectly:
on the rear gears, when upshifting (e.g., from largest/easiest sprocket to 2nd largest/easiest), the chain kind of "hops" from one sprocket to the next -- like it is lifted up too far, and then slams down on the next gear. This creates a slight delay in the shift, and obviously throws off my pedaling stroke. Conversely, there is a *slight* struggle when downshifting (e.g., from smallest/hardest sprocket to 2nd smallest/hardest) -- not as apparent, but certainly noticeable.

So far, based on what I've read, I've cleaned the cables and housing, and tightened the cable tension by loosening the barrel adjusters -- a small amount at first, then about 2 full turns. This has not improved the situation. So is something more than cable tension adjustment required?

thanks for any advice...
