The Controltech CLS Road Stem is designed for road cyclists, sportive riders, and cyclocross enthusiasts who demand a reliable, stiff, and lightweight cockpit upgrade. By utilizing 3D forged 6061 aluminum, this stem delivers superior structural integrity and handling precision compared to standard entry-level components, though it lacks the extreme weight savings found in high-end carbon fiber alternatives.

The Controltech CLS Road Stem has a stack height of 40mm.
Yes, but ensure you follow the handlebar manufacturer's torque specifications and use appropriate assembly paste if recommended.
It is compatible with standard 28.6mm (1 1/8 inch) steerer tubes.
Simply remove the stem from the steerer tube, flip it over, and reinstall it to switch between a +5 or -5 degree angle.
The stem weighs approximately 110g in the 100mm length.
Check that the faceplate bolts are torqued to the manufacturer's specification. Ensure there is no grease inside the handlebar clamp area.
Remove the stem, clean the contact surfaces with isopropyl alcohol, re-apply a thin layer of carbon paste if using carbon bars, and ensure all bolts are properly tightened.
To install the Controltech CLS Road Stem, ensure your fork steerer tube is cut to the appropriate length to accommodate the 40mm stack height. Always grease the bolts slightly during installation to prevent seizing. When tightening the faceplate, use a calibrated torque wrench to apply even pressure across all four bolts, tightening in a cross-pattern to avoid pinching the handlebar. Regular maintenance involves checking bolt tension every few months and inspecting the stem body for signs of fatigue or deep scratches after heavy crashes. Keep the area around the steerer tube clamp free of grit to prevent unwanted creaking.
