Yes I have a stable of bikes because I love to ride. When did I claim I love wrenching? I do what needs to be done the best way I know how and now I will say I enjoy it. I am 'stymied' because I personally have never seen this type before. And because I don't have a 'small hook spanner' in my 3 years worth of tools I am not compitent?

So you looked at my profile to see how old I am? I see you have no personal info posted because you must protect yourself from such attacks. Good job making yourself feel superior to someone who is not afraid to ask questions. Last time I checked thats what Bikeforums was for. You're a big, big man.

As far as I'm concerned you are a 12 year old that talks out of his arse.

So anyway, there is no setscrew. That is an optical illusion.

I'm still waiting on a reply from Bike Tools, then I believe I wil buy the Park spanner.
