Three weeks ago I test-rode an S-Works Tarmac that was fitted with some FSA ergonomic bend handlebars.
The handle bars were so uncomfortable I could barely make it around the block. I forced myself to ride a 1.5 mile circuit, but it was like pulling teeth; I couldn't wait to get off that bike. And it was entirely due to how uncomfortable the handlebars were.
The placement of the drops forces you to grab the brake levers from beneath rather than behind. This puts unnecessary strain on your wrists, as well as making you feel more stretched out than you are (or at least more than you need to be).
Just couldn't find a place on those bars where I could imagine myself holding on for more than a few seconds at a time.
