3T Ionic 25 Pro

3T's Ionic aluminum seatpost is stiff, durable, and features their Driftlock seat clamp assembly for 25mm of setback. This gives you the option of a more rearward position on today’s shorter framesets. The splined aluminum 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.
