Thank you for your thoughtful question.

At most, whatever the difference is in street price between the Shimano GRX Di2 group and GRX group, plus any expense required to build it (which shouldn't be much). Cervelo isn't paying street prices for these groups, so it would be nice if they passed a little saving onto the customer. Somewhere between $500 to $1000. Definitely not $1500.

There are other models in the Cervelo lineup that jump from Ultegra mechanical to Ultegra Di2, the price increases by $1500, but those include upgrades to other bits as well (wheels or bars). The Aspero GRX to GRX Di2 is an example of only the group changing for a seemingly unjustifiable price.

$1500 is a slap in the face.
