The Ionic 25 Pro Seatpost from 3T is made using a new seatpost design featuring the sophisticated and robust, 3T-exclusive DiffLock seat clamp. The Ionic 25 Pro, which is made from a fabricated Aluminium Alloy, places the seat clamp assembly 25mm behind the seatpost’s 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. Available in Black/White with a Shot Peened Black finish.
