I purchased this post because of it's potential adjustability and it seemed like a great post at a reasonable price. I have been a bike mechanic for four seasons and an avid cyclist for almost thirty years. That said, when attempting to install the saddle rails on the clamp, I could not get the rail clamp bolt to tighten to spec (9Nm). After contacting 3t they directed me to a video (that I had already watched) that gave instruction for proper installation. I carefully followed the instructions (again) and worked delicately with the bolt and got it to the proper torque spec. However, the following day on my ride the bolt failed and the nose of my saddle was pointing upward. I had to stop several times to tighten the clamp only to have it repeatedly fail. I have since attempted to contact 3t several times to resolve this situation but no response. I recommend that you don't buy this seat post because of the poor seat rail clamp design and 3t's unwillingness to support their product (in my case anyway).

OMG! and I thought that I was doing something wrong. But after carefully inspecting it seems the clamp is made for flat rails found on some carbon seats. This surely bites! I must say I am very disappointed in the product. I am more disappointed that I cannot return it. That really pisses me off.
