Hi All,
Having changed my cassette and chain I have the gears changing up and down quite nicely on the lower front chainring, however when Im on the larger the gears are hesitant between 4 - 6 whats happening? Help please.

You don't say how many gears you have so I don't know if the position is at the extremes of the cassette/freewheel.

The following advice is for a similar problem but I would have expected both the large and small chainring to have produced similar problems.

When gears change perfectly other than between one, two or three adjacent gears somewhere in the middle of the cassette, the suspect is a kink in the cable. As the kink enters or exits the housing, it offers resistance which typically presents as your problem. It is the first thing once checks before moving to other causes. Remove the cable housing and inspect the inner cable from head to toe. Sometimes you can do that with just moving the little pieces of housing around so that you get a good view. Obviously, a little kink in an area that isn't subject to a slider or a housing, is above suspicion.

Double check that there is no play in any of the cassette sprockets.
Good luck

Two new items fitted I would suspect one or the other.

It's an 8 speed 12/25 rear mesh with 36/50 front.

Is it trial and error or is there a method of checking the tension on my chain?
