- Indexing out on half the cassette.
Is the cable clamped tight enough?
Dounds daft but more than once I’ve been trying to index my gears but its proved impossible, only to realise the bolt that holds the cable to the mech isn’t tight enough. When shifting the cable slips slightly and goes loose, it kind of causes the effect you describe.

Could well be any of the above but (hijack) I experience the same on only one of my wheels and it’s neither of those things that I can find. Have run a new chain, new cassette and new rings but still get 2 middle gears jumping all over the place. Wheel runs true too. Odd.Posted 4 years agogofasterstripesSubscriber
Also – if you fitted the cassette and it was in loose pieces, perhaps remove and refit checking all the spacing rings are aligned and any tabs on them are located in the cassette cogs correctly. That could lead to a change in the spacing between the cogs through the gears.
Might be worth popping into a shop that has that cassette to copy one on the shelf?Posted 4 years ago
