Oh sheesh, how about "If the rings are not flush with where you place the spacers, well then you must add/subtract that distance from each other". Some chainrings are thicker than others. that said, it doesn't have to be exact, you simply don't want to use something much too thick, like a 5mm spacer !

I measured the thickness of the arm "shelves" up which the rings sit. So if the inner ring mounting holes are flush with the middle ring, it's obvious a 3.5-3.6mm spacer will do. I give a range because there are always slight variations of these things. *If the rings are not flush with where you place the spacers, well then you must add/subtract the distance that the middle ring sticks to that.* A digital caliber can measure that distance, if there is any, using the "other end" of the caliper, whatever that thingy is called. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
