How Tight - Carbon Seat Post
Okay so I have one of those carbon fiber seat posts on my new bike. I am ready to make some seat adjustments but I am worried about knowing how tight I should crank the seatpost clamp - I don't want to break the thing - that would make me cry. Is there a large range between tight enough to avoid slippage and shattering the post?
Thanks,
Tobias

turn the bolt in quarter turns until the post does not slip in the seat tube. then back the bolt off 1/8 of a turn. if it slips, put the 1/8 back in. if not, you're golden.
don't grease the seat tube, and clean out the old grease. grease and carbon do not mix well.

Buy a Torque wrench. I think you can get a set at Home Depot for around $20
Then you can tighten it to the right torque and not worry about overtightening it.
I tried using a torque wrench at the bike shop once and had no idea how to use it, the funny thing was that the mechanics didn't know either. Make sure you get a set that has clear instructions. The torque wrench set at the bike shop had no instructions.

OK, here's a question. I ride a Merlin Ti frame. My seat post is a Sycros aluminum. It's nice and light and I have no problems or issues with it since it was installed 4 or 5 years ago. There are a large crop of carbon seat posts out there now, from the Campy models, Deda Black Stick, Easton, USE Alien, etc. Question 1: Will I notice much of a road vibration dampening with the carbon seat post, and 2: which one would you buy?
