Ionic is a new seatpost design featuring the sophisticated and robust, 3T‑exclusive DiffLock seat clamp. Ionic‑25 places the seat clamp assembly 25 mm behind the seatpost's centerline. This gives athletes the option of a more rearward position on today's shorter framesets. The splined alloy DiffLock coupling is a highly-accurate method of setting saddle angle needing only lightweight clamping by side-mounted bolts. It is especially useful for fine adjustment of saddle setback, which can be done without impacting saddle angle.
Ionic‑25 Pro is fabricated in aluminum alloy with a shot-peened, black-anodized finish and the white 3T Pro stripe.
