I have a 2005 Trek 1500 with Shimano 105 triple front derailleur and 9-speed
cassette. No matter how much I fiddle with front derailleur adjustment, I
find that chain rub limits the usable rear gears enough that there's less
overlap than I would like between one chainring (52-42-30) and the next. My
LBS doesn't seem to do any better. This is my first bike with indexed
shifting, and the first I've even owned in almost 20 years, so maybe I'm just
being too picky. But my questions are:
1) With proper adjustment, which rear sprockets should I expect to be usable
for each chainring and trim setting?
2) Same question for a Shimano double with 10-speed cassette.
3) When adjusting the front derailleur, which factors are most important in
getting the maximum number of usable gears? Any special tricks?
Thanks.
