Parts

A stem may not seem like the most exciting bike part, but it's in our DNA to care about it in great detail. After all, no other part has such a dramatic effect on your riding position and thus your speed, comfort, and enjoyment. With the APTO, 60 years of innovation and elegance in 3T stem design comes together in a moving sculpture. Steerer Clamp: Double bolts hold the steerer securely and provide redundancy for extra safety. Reverse Faceplate Bolts: These clean up the faceplate for a more elegant design, particularly in combination with our new drop bars. Classic Rubber Logo: The 3D rubber logo is a nod to the iconic 3T stems of yesteryear. - Material: Alloy 6061 - Steerer diameter: 28.6mm (1 1/8") - Handlebar diameter: 31.8mm - Key size: 4mm Allen key - Steerer bolt torque: 5Nm - Faceplate bolt torque: 5Nm

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 is 350mm long.

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.

Zero25 can handle any type of seatpost rails, including round rails and oval-shaped carbon rails.

The Aeroflux is the ultimate combination of performance and comfort on the road. The newly developed wing shape creates less drag, while the internal cables exit the wing at an angle to ensure they lie tightly next to your stem. For ultimate comfort, the Aeroflux uses our most comfortable drop design, taken directly from the Superergo bars. Drop Grip: The gradual change in curvature makes the grips comfortable for hands of all sizes. The tighter top bend ensures the newest Shimano, SRAM, and Campagnolo shift/brake levers align perfectly for a very comfortable hand position on the hoods. Center Wing: The Aeroflux aero wing cross-section reduces drag where it matters most—at the front of your bike where the airflow is still undisturbed—and it integrates nicely with the 3T APTO stem. Comfort Everywhere: The wing is not only aerodynamic, but it's also comfortable. The increased surface spreads the pressure across your hands and is especially suitable if you rest your thumb on top instead of wrapping it around the bars. - Unidirectional carbon—ultralight layup - Internal cable channels - Stem torque, 4-bolt: 6Nm max. - Stem torque, 2 bolt: 8Nm max. - Shift/brake lever torque: 8Nm max. - Clip-ons: Not compatible (this would require a longer round center section and increase aero drag) - Di2 compatibility: Fully compatible, including with Di2 bar plug Junction A

Designed for gravel racing and fast all-road riding, the Aeroghiaia combines speed, control, and comfort. The speed comes from our aero profile, finally giving you road-bike speed on all possible terrain. Control is enhanced thanks to the flared drops, but the key benefit of the Aeroghiaia is comfort. The aero wing shape provides a large surface for your hands to spread the load, while the multi-angle drops keep the brake hoods vertical (instead of weirdly-angled on regular flares) for comfort. Multi Flare: The Aeroghiaia combines our award-winning Superego grip with a multi-angled flare. The top section of the drop is standard so the hoods are angled as intended, while the lower section has an extreme flare for optimal control. Center Wing: The wing's cross-section is aerodynamic yet comfortable, in particular, when you rest your thumb on top of the bars parallel to your index finger. - Unidirectional carbon—-ultralight layup - Internal cable channels - Stem torque, 4-bolt: 6Nm max. - Stem torque, 2 bolt: 8Nm max. - Shift/brake lever torque: 8Nm max. - Clip-ons: Not compatible (this would require a longer round center section and increase aero drag) - Di2 compatibility: Fully compatible, including with Di2 bar plug Junction A
