The aero bottles/cages are strictly for photos. They were sent to me months ago.
Personally, I am a huge fan of TACX bottle cages. Been running them on all my bikes for the past 4 years and I have never dropped a single bottle. Gonna swap those in before my first ride. And probably add a couple of bolt washers between the cage and downtube.
Maybe I'll put the aero bottles on different bike.
