This is how mine is setup. You shouldn't brake much going into barriers anyways...given they are on a strait away. Just like flargle said, brake with the front (left or right depending how you get off) as you reach for the down tube and it pops right up. It's actually pretty easy to do with about an hour of practice...and I am NO pro.
