The 3T Ionic 25 Pro seatpost is ideal for the self-sponsored cyclist who appreciates a little extra room in the cockpit. The entry level Ionic 25 is called the Pro. It was constructed with aluminum alloy for the entire seatpost and clamp assembly. While this adds a few grams (35 to be exact) to the overall weight of the post, it makes up for it in price. 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 is easy to reach, and you're able to adjust for setback without disrupting seat angle.
