Hi, this is probably a very dumb question, but I am going to throw it out there. A friend bought me an EC90 seatpost (27.2, 300 mm) as a gift. I was checking the easton website, and this post is only listed under the road post category. I know that some posts go both ways (EC70, EC90 zero). Could I use this on a mountain bike (I ride all terrains/styles) or will it snap in half? I noticed that the head is carbon, and this is where I fear the weakness will be. Any thoughts? Thanks.
