The higher-tier one in their new gravel line is 48/31T. (WTF?)
They say that these new cranks change the chainline by 2.5mm, and that requires their new derailleur(s). (also, WTF?)
If you are buying GRX stuff then you probably will be buying a new front derailleur anyway. The extra 2.5 mm is to help with tire clearance.
48/31 actually makes lots of sense when compared to 46/30. 48/31 has more top end than 46/30 and is almost as low. One could say that it is the best of both worlds.
