Seriously, it seems like 9 out of 10 people who try bibs never buy shorts again. I should start a poll...
Anyway, the advantages are:
1. Never having that cold wind (when it's cold out) between your shirt and your shorts.
2. Not having an elastic pressure on your waist when you're riding.
3. Not having to worry about certain anatomical parts showing.
If these don't apply to you, then perhaps you shouldn't buy bibs. All three applied to me.
