Product Information

Full details

The XLC A-Head Stem is designed for both performance athletes and daily commuters seeking to optimize their riding geometry through a highly adjustable interface. Its primary benefit is the extensive angle adjustment range, allowing users to fine-tune their reach and handlebar height for maximum comfort, though cyclists prioritizing ultra-lightweight components may find the 297g construction slightly heavier than fixed-position racing stems.

FAQs

Can I use this on a carbon fiber steerer tube?

Yes, provided you follow the torque specifications strictly and ensure the stem is compatible with the headset assembly.

What tools do I need for adjustment?

You will need a standard set of metric Allen keys (hex wrenches) to adjust the stem angle and tighten the clamp.

Does this stem include a top cap?

No, the package includes the stem only; you should reuse your existing top cap and bolt.

Is this suitable for aggressive mountain biking?

While durable, this stem is primarily designed for commuting and general fitness riding. For extreme downhill or enduro, a fixed-position stem is typically recommended.

How do I ensure the stem is centered?

Align the front wheel with the frame's top tube and tighten the steerer clamp bolts while maintaining that alignment.

Troubleshooting

Creaking sound from the stem area

Clean the handlebar interface and ensure all bolts are torqued evenly to the manufacturer's specification.

Handlebars slipping or tilting

Check that the faceplate is installed with an even gap and that the clamping bolts are tightened in a cross-pattern.

Pros and Cons

Pros

  • Extremely versatile angle adjustment for comfort
  • Durable cold-forged aluminum build
  • Standardized sizing for easy component swapping
  • Reliable clamping force for secure handling

Cons

  • Heavier than static lightweight performance stems
  • Periodic maintenance required to prevent bolt loosening
  • Adjustment hinge may accumulate dirt over time

Setup, Compatibility & Care

To install the stem, ensure your bike uses a 1-1/8 inch threadless steerer tube. Slide the stem onto the steerer, secure the handlebar clamp, and torque all bolts to the manufacturer's recommended specification.

Compatibility Checklist:

  • Steerer Tube: 1-1/8 inch (standard for most modern mountain and road bikes)
  • Handlebar Diameter: 31.8mm (oversized standard)

Care Instructions:

  • Regularly check the adjustment bolt for tightness, especially after the first 50 miles.
  • Periodically wipe the hinge area with a dry cloth to prevent grit buildup.
  • Apply a light layer of grease to the threads of the adjustment bolt to ensure smooth future movement.
