I’m having an issue with ghost shifting with indexed downtube levers. It tends to shift up into a higher gear, by itself, only when out of the saddle or setting off from lights.
There are a few comments online that blame the shifter not being tight enough (it is), friction in the shifter cable (newly-installed, oiled), or a broken frame (steel frame, no cracks or anything).
If anything, the cable seems really smooth, and the frame’s not particularly flexy as far as I can tell.
Is there anything I can do other than tighten up the shifter? If I tighten it up enough to stop it happening, it feels way too tight to actually shift.
Could a too long chain do this?
Thanks!
