Thanks everyone for the great advice. I ordered the TruVativ Hussefelt handlebars as Frank Cannon suggested, and I also ordered a set of Ergon GP1-L grips. I think the standard type should fit. I just put the bars on the bike and they feel great riding around the block, and I am looking forward to trying them out on a ride this weekend.

Here is a pic of both the old and new bars (top)
