I've had my Schwinn High Timber F5 mountain bike for probably 15 years and decided to replace all the cables. I've also already borrowed the rear wheel from my guest bike while I figure out how to properly true up the old one (another question will be coming on that).
After replacing the cable and wheel, I cannot get the shifting to work properly. It always skips a sprocket on the way up and down the cassette, never skipping the same sprocket in either direction. I've successfully indexed my gears before, but I cannot get them indexed with this new cable.
Things I've done to the bike so far:
- Straightened out a very bent derailleur hanger with the Park Tool DAG-2.2 Derailleur Hanger Alignment Gauge. I wonder if my derailleur had somehow adapted to the bent hanger or was adjusted accordingly at the bike shop when they installed it. Now that I've fixed the hanger, could it be causing indexing issues?
- As mentioned, replaced rear bike wheel. I've had this wheel on my bike prior to replacing the cable and it shifted no differently. The cogs are identical in size and spacing so far as I can tell
- Ensured that the limiter screws are properly adjusted
Thinking of just buying new derailleurs, but am hoping I am just doing something wrong.
