Brake reaction arm vs speedo drive
Hi guys, well I have not used the XFD yet, but in most cases the reaction arm (pork chop) goes on the left hand side of the bike seen from where you are sitting on the bike.
Most of the time, the Whizzer speedo drives were mounted on the right hand side (again, as seen from sitting on the bike).
In the case that the little tabs do not go in-between the spokes, ANY method of being sure that the arm with opposing tabs spoins with the wheel, so long as it does not "load" too much pressure onto the drive, will work.
I have used the Whizzer speedo drives on other applications before.
Let us know how you make out.
Mike
