very nice photography of a great looking bike.
Since you know Aero is where it's at, who cares about a pound or two? I like your

Cervelo more than the average

Is that carbon saddle uncomfortable?
If I had your bike and wanted to shave weight I would consider a fork upgrade, maybe 3T Funda Pro or Edge Aero if it comes in the right rake.
I read in an old post that your fork may weigh as much as 650g (I can see the AL steerer tube for sure)
viewtopic.php?f=3&t=26227Going with 3T or Edge might shave 300g -
Keep the old fork in case you go back to aerobar mode.
