A stem may not seem to be the most exciting bike part, but it is in our DNA to care about it in great detail. After all, no other part has such a big 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 come together in a moving sculpture.
BARFLY COMPATIBLE: The Apto Stealth stem is compatible with the Bar Fly Race Direct GPS mount.
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, in particular in combination with our new drop bars.
CLASSIC RUBBER LOGO: The 3D rubber logo is a nod to the iconic 3T stems of yesteryear.
