Campagnolo query

bianchibob

Hi everyone, I am fairly new to cycling and have just acquired a Bianchi 928 with Campagnolo Veloce groupset ( 9 speed) I am very pleased with the look and the build quality, and the quality of the groupset is super smooth comapared to my other bike a Specialised Allez with Shimano Sora groupset.
I have just upgraded the Khamsin wheels on the Bianchi to Campagnolo Eurus G3 and they have come with a Chorus cassette again 9 speed. I have now noted that after installing the wheels the change both up and down is not as refined as before on the veloce groupset.
My question is, do I need to have the Veloce derailleur reset or tuned to the Chorus cassette to get a better change or would I be better replacing the Chorus cassette with the original Veloce cassette from the original wheels.

Chances are it is just the rear derailleur that needs a slight tweek. Have a look at the high and low limits, and also cable tension.

Yes, simple re-tune of the rear mech- probably just the top and bottom limit screws. Plenty of online tutorials on youtube.

Is the Chorus cassette new? It may be worn out. If it is new you may need a new chain to go with it.
