3T Ionic 25 Team Carbon Road Bike 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 Team has a carbon-fibre shaft bonded into an alloy head and is finished in high-gloss black with the 3T Team red stripe.
