3T Ionic 25 Ltd Carbon Seatpost

Ionic is a new seatpost design featuring the sophisticated and robust, 3T–exclusive DiffLock seat clamp. Ionic–25 places the seat clamp assembly 25mm 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.
