I have a Felt Z-100. Owners manual is not much help, seems most things I need to know say, "This particular part is adjustable. Return to your local bike shop for assistance".
I need to raise the handle bars. On my other bikes, you just loose the hex head screw on top of the handle bars and that loosens it. But that's not how the Felt works. The hex head screw just holds a cover on. See the attached photos.
Photo on right is with cover on, photo on left with cover off.
How do I adjust it?
