Talking about PassQuest, I do not have a particular good experience.
Tried their 33/46 2x option (non-flattop version), had a very hard time shifting to the bigger chainring, no matter how many times I tried to tweak the Di2 FD.
Maybe I need an adapter to further lower my FD.
Meanwhile I'm running 33/48 2x from Stone, way better up shifting, not as perfect as Shimano chainrings but very close, even without an adaptor to further lowering the FD.
