Easton makes the EC70 carbon fiber seat post. It costs $100.00 USD. It has been rated very low in most magazines, and is rated low on the web as well. I have seen a snapped one. Sure it is very light, but is it worth it to break a 100 dollar seat post. You might also have to take a trip to the hospital. Carbon fiber splinters in my ******* sounds very unpleasent. Please use caution when using this seatpost!!!

What a bunch of hogwash,, I have one and its just fine, and where did you see one snap other than Windows Paint program where you made this picture up? geeesh......
The EC70 CF seat post weighs 155 grams while the Campy Chorus TT weighs 190. If your worried about the CF seat post snapping why not get one made of titanium and end any thoughts of it breaking? The extra 35 grams of weight you will never notice especially since it's not rotating weight.

April '04 issue of Mountain Bike Action.
but i've effed up too many seatposts over the years to buy one made of carbon; i don't want anything that has a material tendency to catastrophic failure...
This is additional evidence that consumers are demanding fragile racing equipment in a quest to eliminate every "excess" gram of weight. I'll keep my somewhat heavier aluminum seat post and its safety margin.

ok...then don't buy one...
I'd still buy one though, but then again, I am a roadie. the main deterrent to me is just cost.

Get a Thompson, they weigh more but will last longer than your bike will. Don't be a "weight weenie".

The reviews on most websites are mixed, either you hate them:
If your prep your frame a little, you'll be fine. File off any sharp edges, turn the coller 180 degrees, torque to spec."
I've known mechanics who swear they don't need a torque wrench to tighten things up. Any time I've ever challenged their "calibrated arms" they've been way off the mark. And torque wrenches help cure a variety of ills created by lazy mechanics like headset and bottom bracket creaks and stickiness, stripped out stems, Etc.
The clamping forces obtained with a torque wrench are very dependent upon the condition of the threads: dry, lubed, lubed with what?, etc. The only way to accurately determine clamping force is by measuring bolt stretch. I use a torque wrench for consistency, but frequently tighten my carbon seatpost using my "calibrated elbow". I've never had a problem.
