Shimano 11 speed component combinations I want to upgrade my bike to a 1x system using a Shimano GRX-crank upfront.

I however have a flatbar and can thus only fit flatbar shifters.

What is the lesser evil?


11-Speed XT derailleur with XT shifter and GRX crank
11-Speed GRX derailleur with XT shifter and GRX crank


Thank you in advance.

EDIT: I forgot to mention that everything including the rear wheel and cassette will be new.
I have found that Shimano offers non-series road flatbar shifters such as the 11-spd SL-RS700.

So this one can be used with GRX-derailleurs, as GRX is compatible to all roadbike components Shimano offers.
