|I have a recently built Cannondale CAAD5 that has an American Classic aluminum seatpost. I lubed the seatpost with grease before putting it in the seat tube. It's been slipping down into the seat tube throughout rides, and I'm afraid of overtightening the seat tube collar.
Is there a guideline for how tight you can crank a seatpost binder?

|Examine the sides of the slot in the bike's seat tube. If they're not parallel that may be a sign that your seatpost is too small. I'd try a seatpost that is 0.2mm larger.|

|Many, many times there is no grease on the clamp bolt and when you tighten it down, you don't get enough torque on it. Grease that bad boy up, crank it down and I bet you'll be fine.|

|Lube the statpost bolt also. Sometimes seatposts are mis-marked and sometimes seattubes are mis-sized. Have someone measure both with the correct tools.|| |
