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 Team Stealth has a carbon fiber shaft bonded into an alloy head and is finished in our elegant Stealth livery.
