i am planning on upgrading my dahon boardwalk handle bar and would like to ask what and how can i best tackle this ? i am attaching a photo of the original handle bar. as you can see from the pic, it has a lock so you can adjust it horizontally. i didn't want to put a drop bar as it will cost me more since i need to get a different shifter and the brake lever for the drop bar are more expensive than the regular lever. couldn;t find a previous post and if this is a repeat pardon me and kindly send me the link. i know that some have done this and have been successful. appreciate it.
