3T Apto Stealth

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.
