I’m also interested in this because his position is a lot like mine. And this was a “POSITION” question, not an “aero gear” question. So - aside from his incorrect gear, what about his position?
Seriously, do u want to know why no one has responded to the positioning issue…? Because the pics are not the best to tell regarding the positioning. At least set the bike up on the trainer (with pics taken from the side) at home is there is no spectator pics (taken from the side).
Going without gloves is a good suggestion. Your racing top is a trifle on the baggy side. You may want to investigate a more form fitting one or a one piece suit.
You are doing more right here than wrong by far though- the drinking system was a good move as is the aero helmet. Well done!
