how much did you get these for if you don't mind me asking
They were $370 and I can return them.
what would make you think that a group lower but newer would be better?
2010 Rival has zero loss and reach adjustability; I don't think my Force has those features. I'm thinking of running a compact road crankset and am not sure of what benefit the 2010 Rival trim position on the big ring would give me. If this sounds wrong, please let me know. Admittedly, I'm very new to this and it's why I'm here. Thanks for the help ID'ing these components.
