• First time trying to install campag 12 speed groupset and front derailleur has a chain rub.

    Front small ring - last two cogs in the back - chain rubbing inner plate
    Front big big - smallest 2 cogs in the back - chain rubbing outter plate

    Feels like front derailleur doesnt have a amplitude for the whole rear cogs. Is it normal for 12 speed gruppo or am I missing something?

  • You’d never want to go small/small on the sprockets/rings anyway, but you can trim the front mech by a click to move it away from the chain.
