The Iconic Ionic

If a zero millimeter setback doesn't quite give you enough reach in the cockpit, try 3T's new Ionic 25 Team seat post. This carbon post is lightweight, stiff, and features 3T's easily adjustable Difflock seat clamp. 

The Ionic 25 Team was constructed from a combination of carbon and alloy. The post itself is carbon fiber. This provides a stiff platform for your saddle that also dampens road chatter to make your ride more comfortable. The setback is 25mm, which gives riders a more relaxed position and is also an ideal compromise on a frame with a more aggressive seat tube angle. Sitting on top of the post is 3T's Difflock saddle clamp. This is a single bolt clamp that allows for quick and easy adjustment of both saddle angle and fore-aft position. The hex key both is easy to reach and you're able to adjust for setback without disrupting seat angle.

The 3T Ionic 25 Team seatpost comes in two widths: 27.2 and 31.6mm. Each width is available in two lengths: 280mm and 350mm. It is finished in black with a red stripe.

Good Ride

  • Familiarity: I've used it once or twice and have initial impressions

But on the heavier side. The clamp is very secure, but the internal mechanisms don't allow for much precision on dialing in your saddle angle. It is very stable once installed and helps provide an exceptionally smooth ride and would be an excellent carbon post for heavier riders as it is very sturdy.
