My bike has 2009 Campagnolo Veloce 10 speed drivetrain. I recently changed the cassette (still Veloce 10 speed) and chain (campagnolo Record 10 speed). I assumed the fact that the chain was in the Record series wouldn't matter since it's still 10 speed.
However, I can't get the new setup to shift well. If I tune it so that it downshifts smoothly, it's noisy while pedaling (unless I exert a small force on the upshift lever). If I tune it so there's no noise while riding, it won't downshift properly.
Further reading of the Record chain says it's "Ultra narrow" so I'm wondering if that chain isn't compatible with the rest of the Veloce drivetrain.
Is my issue adjustment or compatibility?
