Just looking at the stock set up on the kilo makes my 45 year old back hurt... but I can ride all day with drops when they are set up right.

And I have a really bad back... am often too crippled up to walk any distance but riding offers much relief.

My brake hoods tend to be level with my saddle so those raise the flats a little above my saddle and I have a higher drop position that I can stay in for longer periods. If I get too low I really start to have back issues and cannot sit upright for any distance at all.

Also like my trekking bars a great deal... I don't there is a better bar out there for long distance riding unless you really like staying in the drops all day.
