SRAM Red Front Derailleurs
I have had zero luck with them. I love the Red gruppo but the cage is not strong enough and bends when shifting from the small ring to the large ring and thus does not shift. Pain trying to go up a hill in the big ring. Called SRAM and got them to admit they are looking into this especially after I learned Cancellarra uses a SS SRAM derailleur. Switch to SRAM APEX SS and it shifts smooth. Red needs to figure this out. Other than that, I love SRAM Red and would only consider the Di2 gruppo if I wanted to dump the coin on it.
