I just had mine off last week. The key is patience. If you can get it started just a little with a fingernail, then you can work a thin object under them and lift. Work your way around each caps, lifting from several positions.
Cheer up.
Getting them back on is a snap.
However, you might want to leave the caps in a baggie in your tool box until you are certain that you have the bars where you want them.
Don't ask me how I came by this pearl of wisdom.
I should have the bandaid off my finger in next few days.
