Bought some of these and upon fitting them today after I'd been for a blast, however I'm convinced they are missing an adapter or have the wrong left hand bobbin. The right hand bobbin securely locates in the replacement end screw/nut but the bobbin on the left (looking down from the riding position) just flops around on the M6 rod until tighten'd up and is pulled up against the open end of the spindle? Should this bobbin not have a protruding formed bit that sits in neatly inside the open end spindle like the RHS one does for the supplied nut which then keeps the M6 rod central located within the spindle?
Right, first picture is the offending left hand side bobbin which does not locate centrally inside the wheel spindle. Second picture is the same again but removed so you can see that the small round protrusion that sits inside the spindle is not big enough in diameter. Last picture is of the other side (right hand side) which does sit neatly and centrally over the supplied replacement spindle nut.
I have r&g bobbins same sort of concept replacement nut with hole in the other side I'm sure has a big locator that fits inside the hole to hold centre ish
