Campy 12-Speed Mechanical RD Question

[Jeff N.]

How many of you who're running Campy 12-speed have had to markedly screw in the fore-aft adjustment screw (NOT to be confused with the in-out limiter screws) to obtain proper function into the 32T cog?

No matter the RD or cassette size (assuming the RD can handle the lowest gear to begin with)....I always fiddle with the B screw (what you're referencing) to get the top jockey wheel withing the prescribed 5-6 mm or so from the biggest cog. Eyeball it, or use your 5 mm tool for checking spacing.

Perfect. Thanks.
