Not necessarily, and it may not work at all if you can't get the bars
high enough. A small-size bike is a problem, unless it has a long
head tube and upsloping toptube, perhaps.

Unscheduled get-offs are more common in cross than on the road, but not
an issue for commuting and dirt-road riding. Still, standover is never
really the first priority in bike fit - you rarely straddle the bike
dead upright in your socks.
