My brother has an Ultegra triple. He had the LBS "disengaged" the granny gear, so the he can't shift into it, since all of his rides have been on flats. Now, he wants it engaged so he'll have it doing hills.

I thought that they just simply moved the L-limit screw way over so you can't shift into the granny, but I was wrong (I think). I tried moving the L-limit screw back to allow it to shift to the granny gear, but I ran out of room on the limit screw. I unscrewed the limit screw all the way and it's not even close to shifting to the granny.

Does anybody know how the disagaged the granny gear?
