Ionic is a new seatpost design featuring the sophisticated & robust, 3T–exclusive Diff Lock seat clamp. Some frame designers are also specifying a slacker seat tube so riders can set their bike up with an inline post, which is lighter than a setback post. The splined alloy Diff Lock 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–0 Team has a carbon-fiber shaft bonded into an alloy head & is finished in high-gloss black with the 3T Team red stripe.
