Well, as this problem was playing on my mind, I decided to go out and actually try the widget.
I couldn't get it to work, either!
My 1100 has ABS ring, and a standard exhaust. As Popeye said, it seems far too long to allow the wheel to be got vertical - and then to slide onto the "bar".
I even tried it at the 3 oclock and 6 oclock positions - but neither position would allow the wheel to be got vertical - between the tyre hitting the exhaust, and the hub hitting the "bar".
I tend to think that it could do with being 40mm shorter - bearing in mind the threaded section seems to be longer than necessary - I reckon about a 10mm thread length would be ideal - on mine there is still a good section of thread showing with the tool fully screwed in - or at least far enough in to be able to remove it easily with a flat spanner when the wheel is in place.
As I see it, the "bar" only needs to be long enough to have about 20mm protruding, including the flats, with the wheel in place, to allow you to unscrew it with the flat 10mm spanner - or maybe I'm missing something here? Please discuss.
Not having a go at you, Jaws - this just seemed a better place to iron out any fixes needed - more heads to come up with ideas!!
