3T Ionic 25 LTD Road Bicycle Seatpost

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 Ltd is a monocoque in high modulus carbon fiber, finished in high gloss black with the 3T Ltd silver stripe. Note: Standard DiffLock seat clamp fits only saddles with 7 mm round section rails. Saddles with oval rails require oval rail clamp caps. Certification: CEN.
