[Closed] ghost shifting

Clean cables, or replace.

tell the ghost to get his own bike!! 😉

done that, just can't get it not to. so bloody frustrating, maybe i need to spend some time ultra fine tuning the derailleur

does the cable route tightly at bends

Pop the ferrules of the cable sleeves and trim the pointy out wires back.

Have you got too much or too little cable? Especially the section where cable goes between the main frame and "swinging arm". I'm assuming you're not running full outers.

check cable runs,kinked cables as suspension compresses actually can pull some cable and change gear. how old is the cassette?, worn cassette will cause chain skipping

Had this recently myself, it was only doing it a bit but enough to be annoying, I had bought myself a new frame so swapped all the bits over addng new cables, still ghosting, its was time for a new drivetrain, that didnt solve it, I bought a new mech as I wanted a medium cage anyhow, so thats was it the whole damn lot changed except the shifters and it still ghosted occasionally, in my case it was the very last thing and clean and re lube of the shifter itself had it perfect again.

Yep, check the outers are long enough to account for suspension movement and not snagging on anything.

Also check your mech hanger isn't bent. Even a tiny bend can cause odd shifting problems. Take it off and put it on a flat surface to check.

thanks for all the advice. that's my forum cherry well and truly popped. cheers, will try some of the stuff, sounds like it could well be cable length, was used to hardtails.

Also make sure any bolts on links/pivots are the right tightness as a bit of flex/movement under pedalling can get the ghost going.
