So, you are mixing and matching triple chainrings. Does this work for all variations of triple chainrings? If I have a middle chainring that is ramped and pinned so to be a middle in a triple, does it matter whether this is matched to the inner chainring? To the outer? Adam at Prasix stated that when they get a matched tandem chainring set the shifting would be
magnificent. He thought maybe the double outer chainring he sent
might work. I've found that this double outer chainring works better than both the triple TA and Dura Ace outer rings.
I still don't know if it matters none, sometimes, little or considerably whether the outer chainring on a triple is double- or triple-specific, or designed to work with the particular middle chainring.
