I have a hamburger drum and a 35mm Showa front end. Hoping someone can help me work out the offset for this?
I have a 19 WM3 wheel it's laced to.
I tried doing offset for a steel rim as per the FSM (see pic attached), which is 1-7/16" (1.4375) from the top of the bit the bearing is in that sticks out, to the spokes of the rim's drop centre... But when I put the wheel back in my forks, the tire is so close that it's rubbing on the forks (it's close on the side opposite the where you set the offset).
So it seems I need less offset, but is there a way to work out how much less? Or am I doing something real dumb here?? (very possible)
Have attached some pics of the FSM, how I'm measuring it (1-7/16" is about 36mm), the tire gap (sitting hard against left fork), and the gap between my forks.
