3T Ionic 25 Pro Comfort Seatpost

Ionic-25 Comfort enhances the standard Ionic-25 post with shock-absorbing technology. A polymer damping ring between the head and the DiffLock clamp decouples the head from the shaft of the post, preventing high-frequency vibration from being transmitted to the rider.

Ionic-25 Comfort helps reduce rider fatigue on today's generation of ultra-stiff, aero race bike chassis, and bikes intended for endurance riding. Pro version is fabricated in aluminium alloy with a shot-peened, black-anodized finish and the 3T Road Circle in White.

Note: DiffLock seat clamp fits only saddles with 7mm round-section rails. Saddles with oval rails require Ionic oval caps.
