Yeah, I thought the rear derailleur suggestion sounded a little odd. I worked OK when the bike was running with grip shifts.

There is nothing impeding the travel of the lever. It has full motion from past the full down position to just higher than horizontal (maybe 100-110 degrees of motion).... the same as with no cable attached. I've set the low stop screw to a setting that limits the travel of the derailleur to where it is centered over the small chainring, and the high stop to where the inside cage arm will be centered over the large, if forced by hand. The problem is, the shifter won't pull enough cable to move the derailleur far enough outboard.

With the lever pulling as far as it goes, the outside arm of the cage goes maybe 5 mm past the largest chainring. So, it shifts onto all 3 chainrings just fine, but doesn't go far enuff past the large for the chain to clear the cage when the chain engages the 2 smallest cogs.

Pehaps I'll try setting the low stop screw to limit the travel of the der. a bit more, and try taking up the cable more. Again. I tried that before, but it affected the shifting onto the small chainring. Perhaps a little more patience....

FWIW, new cables and housings. I've used it enuff to stretch the cables.

Thanks for the input guys. I'll keep ya posted.
