3T Zero25 Team Stealth is a lightweight carbon, universal seatpost with a twist: it’s two seatposts in one. The two clever, reversible saddle rail clamps transform the post from zero saddle setback to 25mm setback. All that’s needed is to flip the clamps from one side of the seatpost head to the other and the offset changes.

  • Carbon fiber seatpost shaft
  • Adjustable offset/setback: 0mm or 25mm
  • Requires T27 Torx wrench

Specifications:
Diameter: 27.2mm or 31.6mm
Length: 350mm
Offset: Adjustable (0mm or 25mm)
Material: Carbon
Color: Black
Weight: 215g

3T Zero25 Team Stealth Seatpost (Black) (27.2mm) (350mm) (25mm Offset)
Great Idea, Poor Execution

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). Note: I did not purchase from Nashbar, but now wish I had. I believe that they would have supported my purchased.
