anyone familar with these? it's not a regular binder bolt that secures the seatpost, but instead it's two triangle wedges that somehow tighten the seatpost in place by a single top bolt.

anyway, i have a specialized frame that i'm trying to secure the seatpost into, and i can't figure out how to tighten this down. unfortunatly when i took the seatpost out, the wedges came apart and fell into the frame so i never saw how they were supposed to go together. i tried a few variations but no dice.

any suggestions?

with the collar and post out of the frame, slide the post through the collar, then use some awesome deductive reasoning to figure out how the whole thing fits together. it's basically two right triangles that, when fitted together, make a rectangle. one of the triangle should have a concave surface on it's longest side, that side fits against the post.

is the whole thing the collar, the bolt, and the two triangles?

i was having trouble keeping the bottom traingle from just sliding down into the frame upon reinstall.
