The 3T Ionic 25 Pro Aluminium Seatpost design featuring the sophisticated and robust, 3T’s exclusive DiffLock seat clamp. Ionic 25 places the seat clamp assembly 25 mm behind the seatposts centreline, 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 aluminium alloy with a shot-peened, black-anodized finish and the white 3T Pro stripe.
