Canti bosses for a Cannondale Headshok Fatty fork

[DMC3000]

Does anyone know what size they use?

The old Headshoks use a non metric thread 5/16"-18tpi. Very similar to M8 but not close enough (do NOT try to bodge M8 bosses in there, you'll ruin the fork).

Re:

That sounds obscure enough to be a pain in the neck. Can such a thing be purchased still?

I think they should be still available. Depending on your budget there's a seller in the states that sells those in the Ti-version (25$ for a pair though...)

Hmmm interesting. The thread is very close to m8 as m8 bolt will go in by a couple of turns.
I ran a m8 tap in one of them to fit an m8 plug for holding the front brake hose.
Obviously my application is not safety critical but the newly cut thread look ok to me.

Re:

brake-stuff.de have those canti bosses in stock. Stainless for 13euro and 7075 Aluminum for 14euro. I would get the aluminum ones (might as well go lighter, and they'll work just fine).

Thanks for the advice and links - I'd have probably just tried a few and possibly ruin the thread otherwise!
