Ionic is a new seatpost design featuring the sophisticated and robust, 3T-exclusive DiffLock seat clamp.
Ionic-25 places the seat clamp assembly 25 mm 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 Team has a carbon-fiber shaft bonded into an alloy head and is finished in high-gloss black with the 3T Team red stripe.
Ionic-0 places the seat clamp assembly in line with the seatpost for zero setback. Many athletes seeking outright speed favor this more forward position on the bike. 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 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-0 Team has a carbon-fiber shaft bonded into an alloy head and is finished in high-gloss black with the 3T Team red stripe.
Note: Standard DiffLock seat clamp fits only saddles with 7-mm Ã˜ round-section rails. Saddles with oval rails require oval-rail clamp caps.
Weight: 0mm setback - 200 g (31.6 mm x 280 mm); 25mm setback - 205g (31.6 mm x 280 mm)
After reading the reviews on a number of carbon seatposts, I settled on getting this one because of its design. I really liked the ability to easily tune the seat position without all of the fiddeling needed on regular seatposts. The design is very light. It is not the lightest out there, but it is on par with it competitors in the same price range. The quality of the construction and the final form is high quality. The engineering that I liked was that I could set an angle on the seat and it would hold until changed. The angle setting is independent of the seat position setting. This may not be for everyone, but for me it solved an annoyance of most seat posts and dropper posts out there that use the same or iterative designs.
