Zero 25 Team Stealth Seatpost

Dialing in the proper bike fit might require a zero-offset post on some frames while others might need a bit of offset depending on its seat tube angle. That's what makes the Zero 25 Team Stealth Seatpost from 3T so great. So if you're switching over to a new build or still dialing in the fit on your current steed, 3T lets you experiment, while exuding its elegant Italian style and functional design into a seatpost that looks great on any machine.

The Zero 25 Team's unique design offers both zero and 25mm offset in the same post with a sleek design with maximum versatility. This allows you to try different saddle positions and easily dial in the fit if you happen to change saddles with varying lengths.

The secret of the Zero 25 Teams multiple personalities lies in its head design. By easily swapping the left and right, internal and external cups, you can achieve a zero offset in one position and have a 25mm offset in the other. Either way, you're treated to a lightweight, unidirectional carbon post with durable stainless steel hardware that works with virtually any saddle rail material.

  • 3t's carbon seatpost that offers 0 and 25mm offsets
  • Unidirectional carbon post and aluminum head shaves grams and boosts durability
  • Stainless steel hardware resists corrosion
  • Sleek design and stealth graphics look great on any bike
  • Available in 27.2 and 31.6mm diameter
  • 350mm length is for road, gravel, or 'cross bikes

    Excellent Seatpost - Have Patience

    I've put it through the wringer

    I chose the Zero 25 when putting together my custom build as I wasn't entirely sure if I'd need an offset seatpost. I wanted the flexibility without having to first try an expensive seatpost that wouldn't work for my bike fit and the Zero 25 fit the bill. This feature wasn't entirely necessary as I left it in the zero offset position, but I still appreciated having the option. The cradle mechanism is admittedly a bit clunky to set up, but after the rails are mounted adjusting the setback and tilt is a breeze. My Fizik Arione R1 Open saddle rails interfaced perfectly with the clamp. I could not speak accurately to the compliance of the post as my steel frame deadened most, if not all, chatter. 3T has some helpful videos on YouTube to walk you through the initial setup here:

    can't get seat to not move

    Tried with oval carbon rails and wasn't able to have the seat clamped and not have any movement. Annoying to set up.


    Will this post accommodate oval 7x10 mm carbon rails. It appears to have two slots to allow both round and oval rails?

    I am using it with a Specialized S Works saddle and it does fit. However, I cannot get the post to hold its tilt position. Slips during rides. going to need to find a different post.


    Will this seat post accept carbon rails?

    I am using the LTD version of this seatpost with a Selle Italia carbon rail saddle and it has worked fine. I agree that initially it did slip a little (until the anti-slip paste set), but I rode this setup for the DK 200, with lots of bumps, and it didn't budge. My suggestion would be to clean the internal mechanism with alcohol, apply carbon paste, tighten to the appropriate torque, let it sit, and then retighen.
