Product Information

Full details

The System EX Adjustable Riser Stem is designed for cyclists seeking to fine-tune their riding position for enhanced comfort and control. Its primary benefit is the extensive adjustability, allowing riders to significantly alter handlebar height and angle. A potential caveat is the need for careful adjustment to avoid over-tightening, which could damage components. This stem offers a robust 6061-T6 Alloy construction, a secure four-bolt clamp, and a versatile adjustment range from -10 to +60 degrees, compatible with 1 1/8" steerer tubes and 31.8mm handlebars.

Extended Product Information

FAQs

What is the maximum handlebar rise this stem can provide?

The stem offers an integrated 60mm rise.

What is the adjustment range for the stem angle?

The stem can be adjusted from -10 degrees to +60 degrees.

What size handlebars is this stem compatible with?

This stem is designed for handlebars with a 31.8mm clamp diameter.

What size steerer tube does this stem fit?

It is compatible with 1 1/8" steerer tubes.

What is the material of the stem?

The stem is constructed from strong 6061-T6 Alloy.

How do I clean the stem?

You can clean the stem with a damp cloth and mild soap. Avoid using abrasive cleaners.

Can I use this stem on a carbon fiber bike?

While the stem itself is alloy, it can be used on carbon frames. However, when clamping to carbon handlebars or steerer tubes, extreme care must be taken to use a torque wrench and potentially grip paste to prevent damage.

Troubleshooting

Stem is slipping on the steerer tube.

Ensure the steerer tube clamp bolts are adequately tightened. Check that the steerer tube is clean and free of grease. If the issue persists, consider using a friction paste designed for carbon components (if applicable) or check for damage to the steerer tube or stem clamp.

Handlebar is slipping in the stem.

Verify that the handlebar clamp bolts are tightened evenly and sufficiently. Use a torque wrench to avoid overtightening and apply a small amount of carbon grip paste if you have carbon handlebars. Ensure both the handlebar and stem clamp area are clean.

Difficulty adjusting the stem angle.

Loosen the adjustment bolts slightly. Ensure no debris is caught in the adjustment mechanism. Re-tighten the bolts carefully to the recommended torque specification. Avoid forcing the adjustment.

Noise or creaking from the stem area.

Check all bolts for tightness. Clean the stem, steerer tube, and handlebar interface. Apply a small amount of bike-specific grease or friction paste where components meet. Ensure the headset is properly adjusted.

Pros and Cons

Pros

  • Significantly improves rider comfort by allowing for personalized handlebar height and angle.
  • Durable and robust construction from 6061-T6 Alloy ensures a long lifespan.
  • Easy to adjust, enabling quick customization on the fly or during setup.
  • Secure clamping mechanism reduces the risk of handlebar slippage.
  • Versatile compatibility with common handlebar and steerer tube sizes.

Cons

  • Requires careful tightening to avoid damaging the stem or handlebars.
  • The maximum rise might be excessive for some riders or bike geometries.
  • Adds a small amount of weight compared to non-adjustable, lighter stems.
  • The adjustment mechanism could potentially develop play over extended use if not maintained.

Setup, Compatibility & Care

Setup:

  1. Ensure your bike is equipped with a 1 1/8" steerer tube and a 31.8mm handlebar clamp diameter. If not, this stem will not be compatible.
  2. Loosen the bolts on the stem's faceplate and the steerer tube clamp.
  3. Carefully slide the stem onto the steerer tube and attach the handlebar, ensuring it is centered.
  4. Adjust the stem to your desired height and angle using the adjustment bolts. Do not overtighten.
  5. Securely tighten the steerer tube clamp bolts in a crossing pattern to ensure even pressure.
  6. Tighten the faceplate bolts evenly, again in a crossing pattern, to secure the handlebar.

Compatibility:

  • Steerer Tube Diameter: 1 1/8"
  • Handlebar Clamp Diameter: 31.8mm
  • Material: 6061-T6 Alloy
  • Colors: Black, Silver

Care:

  • Clean with a damp cloth and mild soap. Avoid abrasive cleaners.
  • Periodically check and re-tighten all bolts to ensure they remain secure, especially after initial installation or significant adjustments.
  • Inspect for any signs of wear or damage, particularly around the adjustment mechanism and clamp areas.
