Seat post slipping...

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 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).

I'm not sure how they used it, but my mechanical instinct says the replacing the seatpost clamp would be stronger. The clamp would create a 1/2 in grasping all the way around to bear the weight and hose clamps have a greater adjustability range, which I think is the main advantage. Granted, the seat tube acts like a seatpost clamp essentially since it's a notched cylinder- you get more force near the notch holding the post than on the other side of the tube. If you put the hose clamp on the post which still using a not quite snug enough post clamp, you're letting the edge of the hose clamp touching the edge of the seat tube bear all of the weight, which I'd be a bit hesitant about. Maybe if you had a second clamp of the thickness of a seatpost clamp it would be ok, but hose clamps are thin with lots of holes and I think it'd eventually buckle under the force (or at least have the potential too).
