Head tube space to relax fork angle ?

Gwood said:

Some time ago I thought I read here about a product that was pretty much a spacer that went
under the head tube. The intent was to be able to use a longer travel fork and relax the angle
of the fork.

I mentioned this to a buddy who has an interest in trying this. Now I can't find the reference. Can
anybody help out ?

I'm confused (but comfortable in that condition...). Since a longer-travel fork also relaxes the
head tube angle, why in the world would you want to add a spacer under the head tube (aka on top of
the fork) to relax it even more???

Besides, I wouldn't trust anything that extended the head tube like that - there's a lot of stress
at the bottom of the HT already, and if you cantilever that force out on an extension, the result
will be predictable (and ugly).

Frame decapitation?

Quite possible. About the best that would happen would be the lower head tube boring would get all
rounded out from the force. The worst would be a head tube failure outright - but either way, you'd
probably be looking for a new frame.

My Voodoo Wanga got pretty slack in the head tube. When my OEM headset started to fail, I replaced
it with a King, and it almost dropped in. I imagine the 853 head tube on my new frame will hold up
better. Not 100% sure, but I think it's been hardened, or heat treated.
