To anyone that has installed Gilles rear adjusters....how much did you tighten the rear most fasteners, the two that hold the little piece on the other side of the swing arm? I think I may have over-tighten them, as I do everything. They kind of look, well, pinched. All the instructions were in German??? I think the nut is actually suppose to be the locking part of the deal but I hate to leave stuff loose...at 175+.
