Strongline sets you’ve posted link to are not available on stock. What’s wrong with Litepro chainrings? Besides that’s it’s cheap.
in fact, some MTB cranksets that use center lock mechanism will work with Birdy with a spider adapter. A lot of my friends are using SRAM MTB, Rotor with extended axle and eeWings MTB cranksets. They simply add a spider adapter and get the chainrings of their choice.
