IMPORTANT:
Ramps on big rings are specially configured for combinations: 50/34, 52/36, 52/38, 53/39T
If you wish to use other configuration it will also work, but shifting will be slower and may require more "adjustments" of front derailleur to be acceptable. Also remember that front derailleur can only accept max 16T difference between 2 chainrings - this is how Shimano and Sram designed them.
