FAQs
Can I use this stem with 35mm handlebars?

What is the weight of the stem?
The weight is approximately 125 grams for the 110mm version; weight will vary slightly by length.

Troubleshooting
Creaking noise from the cockpit
Remove the stem faceplate, clean the handlebar contact area, and apply a light coating of carbon/alloy paste before re-torquing to specs.
Stem feels loose after installation
Ensure the headset top cap is tightened to properly preload the bearings before tightening the stem bolts onto the steerer tube.
Pros and Cons
Pros
- Excellent stiffness for improved power transfer
- Lightweight forged alloy construction
- Versatile reversible angle for custom fit

Setup, Compatibility & Care
Installation requires a standard hex key set and a torque wrench to ensure the faceplate bolts are tightened to the manufacturer's specifications. The stem is designed for use with 1-1/8 inch steerer tubes and 31.8mm handlebars. To maintain the structural integrity of the alloy, avoid over-tightening the bolts. Periodically check all bolts for tightness, especially after the first few rides, and clean the interface between the stem and handlebars to remove grit that could cause creaking.
