Apto Stem

What Our Gearhead® Experts Are Saying:

"I love installing the APTO Stealth because everything lines up perfectly—torque values are low, the faceplate tightens evenly, and the cockpit gets that pro-level clean look. The steerer clamp is solid, the stiffness is excellent for sprinting, and the weight stays competitive across all sizes."

The APTO Stealth stem brings together 3T’s long-standing stem design heritage with clean integration and robust performance. Its 6061 aluminum body provides an ideal stiffness-to-weight ratio, maintaining responsive handling under load while keeping overall cockpit weight trim. The reverse faceplate bolt configuration streamlines the frontal area for improved aerodynamics and true aesthetic minimalism—especially when paired with modern aero drop bars.

A dual-bolt steerer clamp delivers consistent, even pressure for secure bar control on both road and gravel setups, and the stem remains fully compatible with standard 1 1/8in steerers. Available across a wide range of lengths, it allows riders to dial in precise reach and fit adjustments critical for comfort and efficiency. Bar Fly mount compatibility further enhances cockpit functionality without compromising the stem’s clean appearance.
