Seatposts

Ionic is a seatpost design featuring the sophisticated and robust, 3T–exclusive DiffLock seat clamp. 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. The Ionic–0 Pro is fabricated in aluminum alloy with a shot-peened, black-anodized finish. - Aluminum shaft with alloy Difflock seat clamp fits only saddles with 7mm round-section rails - Clamp Style: Standard Rails - Color: Black - Weight: 230 grams

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.

Zero25 is a lightweight, universal seatpost with a twist: it’s two seatposts in one. The two clever, reversible saddle rail clamps transform the post from zero saddle setback to 25mm setback. All that’s needed is to flip the clamps from one side of the seatpost head to the other and the offset changes. No more problems with getting the wrong seatpost or needing another one when you change the type of saddle you use – it now takes 30 seconds to transform your seatpost. And the best news is that despite the double functionality, the Zero25 is even lighter than our previous seatpost. Zero25 Pro has an alloy pillar and comes in two diameters, 27.2mm and 31.6mm, and one length, 350mm.

3T's Stylus is a fresh take on the 2-bolt aluminum seatpost. The transition from the pillar to the saddle clamp assembly is a finned, rearward swoosh suggestive in shape of the classic one-bolt posts of yore. But the clamp bolts are deployed to either side of the saddle-support cradle, conferring greater stability and easier adjustment. The Stylus 25 places the seat clamp assembly with 25mm of setback for a rearward position on the bike.
