Seat post slipping...

[Thorn]

ah...

is the hose clamp supposed to replace the seatpost clamp? Or is it supposed to go above it, preventing the seatpost from slipping into the down tube?

That is priceless. A $5000? bicycle requiring a 50 cent, non carbon fiber, hose clamp? I'm sure it works. I've successfully used a hose clamp to "patch" a broken rack (still works).
