A stem might not be the most thrilling bike component, but at 3T, we're passionate about getting every detail right. Why?

**Specifications**: Made from Alloy 6061, with a 28.6mm (1 1/8”) steerer diameter, 31.8mm handlebar diameter. Requires a 4mm Allen key, with 5Nm torque for both steerer and faceplate bolts. Finished in Stealth Black for a cool look.



Using your 3T Apto Team Stealth Stem is easy. First, make sure you have the right tools - a 4mm Allen key. Loosen the steerer bolts and slide the stem onto the steerer tube of your bike. Adjust the angle to your preferred +/-6 degrees for the perfect riding position. Then, tighten the steerer bolts to a torque of 5Nm. Next, attach your handlebar to the stem and tighten the faceplate bolts to 5Nm as well.
When using the Apto Stealth stem, always check the bolts regularly to ensure they're tight. If you're using the Bar Fly Race Direct GPS mount, make sure it's properly attached.
For maintenance, keep the stem clean by wiping it down with a soft cloth after each ride. Avoid using harsh chemicals or abrasive materials that could damage the finish. If you notice any signs of wear or damage, replace the stem to ensure your safety.
