Just built up an Air9 – using a normal M770 XT front mech I coudln't get the leading edge of the mech cage to sit within the normal height above the outer c/ring teeth without the trailing end of the cage touching the teeth (ie as if the mech had been rotated slightly anti clockwise from its normal position).

Make me think I should be using a trekking type mech to suit shallower seat/cstay angle – anyone else had this problem (nothing I could find on niner site)?
