For me, I'd definitely say dips. I hit a "tire-sized" dip down next to
the bike path -it was a speed dip of some kind - and my 28" tire
totally stopped turning, and off I went. I think bumps are easier
'cause you can kind of hop up, but dips are tough because you have to
climb back up out. Sucks to UPD in front of a bunch of people, cause
of a traffic dip. Not the B.C kind.
