Just got a new ultegra rear mech
out of the box and notice that the
upper pulley wheel does not spin
as freely as the lower one.
There is just a slight drag.

Can anyone confirm something
similar with theirs??

    If i remember correctly one of the jockey wheels runs on a sealed bearing likein your hubs and the other jockey wheel runs on a ceramic bearing.
    The ceramic bearing isn't quite as free as the sealed one.
    I'd say what you are describing is perfectly normal
  • Great thanks, just noticed that upper
    pulley is ceramic...
