|three weeks into the plush comfort of a specialized carbon seat post on my jittery cannondale and the post is cracked at the seat collar.
i know $70 isn't an expensive carbon seat post, but i'm a 6'7" , 210lb sprinter so i bought a beefy mtn. bike post with an extra 100 mm of stem length to get a beefy post.
i followed the torque suggestions, but it cracked vertically, anyway
can you break a seat post sprinting?

|Many CF seatposts are designed to be clamped in a certain area that is reinforced. I don't know about Specialized ones, but if your seatpost is way long then you may not be clamping it in the proper area.|

|I'm 180lbs and I cracked a USE, from clamping it to tight. I personally don't think the CF posts add anything in terms of feel and I like the reliability of something that I can install and forget about. . . . like a Thomson post. If you cracked in vertically, its probably from too tight clamp pressure.|

|I don't know whether it really helps (it should in theory) but you could give the Campagnolo asymmetrical seat post clamp a try. I got one on my Cannondale as well and an ITM carbon post.|

|My crappy Campagnolo Record carbon post also cracked. No warranty, blame the rider, etc...
I wrote a damning review to RoadbikeReview and found out that many riders have had similar problems. Now I'm happy with a Thomson Elite post: 15 grs. heavier but much cheaper.
