Worn casette?

Hi

Having trouble accurately indexing my gears on 10 speed casette. I'm normally pretty good at this job but this time struggling because the shifting from 2 to 1 doesn't seem to work while shifting between the other from 3 to 10 and back again is fine.

Limit screws are set correctly but if I change the tension slightly then shifting from 1 to 2 doesn't happen and then it jumps straight to 3 and works fine from 3 to 10.

Is this a sign my cassette is worn or something else?

    More likely to be something is bent or the cables are past their best.

    Hav you set the B screw/chain gap?

    When this happened to me before my gear cable was sticking.

    Are you having problems with the 2 smallest gears?

    First check is always cables. Cheap and easy to replace -inners and outers.

    Also checking the mech pivots are moving freely, a clean and light lube can work wonders.

    I’d have said it’s more likely to be a problem with the cable. It might be snagging somewhere along its route. Check the little plastic guide under the frame, at the Bottom bracket isn’t all chewed up, that’s a good source of cable snags.
