It isn't though. As I'm sure someone with your knowledge and experience will already understand, it is perfectly possible to adjust the inner and outer limits of the FD independently of each other.
For instance, SRAM 2x10 and 2x11 drivetrains are capable of running big/big crossover routinely - but I'm sure you already knew that.
"It isn't though." - That's a very hollow counter argument you present. Being in those gears is bad for more reasons than it is good, particularly if you actually your desired cassette gear ratios set up. I don't know why you're trying so hard to hold onto something that clearly is not making any good sense.
Yes, you can do that with the FD... that's kind of the point with the limiter screws of them being independent....I don't think you understood what I said..
They're capable of this? every bike is capable of that. Whether it's advisable for the health of your drivetrain however, is another question, a sacrifice not worth making for any reason.
Also, what does it matter if Said Sram 2x11 is able to do this
without any problems This makes no sense in relation to the OP or his bike.
