FAQs

What size handlebar does this stem require?

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

What is the main benefit of the wider stem body?

The 56mm wide stem body significantly increases torsional stiffness, leading to more direct steering control and improved front-end accuracy, especially on challenging terrain.

Is this stem suitable for carbon handlebars?

Yes, it is suitable for carbon handlebars. Use of carbon assembly paste is recommended on the handlebar surface within the clamp area to prevent slippage and damage.

What is the weight of the Renthal Apex V2 Stem?

The exact weight varies slightly by length, but the extensive internal machining contributes to a lightweight construction suitable for performance builds.

How do I clean and maintain the stem?

Clean with mild soap and water using a soft cloth. Periodically check and re-torque all bolts to ensure secure clamping. Avoid abrasive cleaners.

What lengths are available for this stem?

The Renthal Apex V2 Stem is available in 31mm, 40mm, and 50mm lengths to suit different rider fit preferences.

What type of aluminum is used in its construction?

The stem body is made from 2014 aluminum, and the faceplate is constructed from higher-grade 7050 aluminum for optimal strength and durability.

Troubleshooting

Handlebar slippage

Ensure handlebar is clean and free of grease. Use carbon assembly paste if applicable. Check and re-torque faceplate bolts to the correct specification (typically 5 Nm), tightening in a crossing pattern.

Stem creaking or noise

Check that all bolts are torqued correctly. Apply a small amount of grease to bolt threads. If using carbon components, ensure carbon assembly paste is applied correctly.

Steerer clamp not secure

Ensure steerer tube is clean and free of debris. Verify stem is fully seated on the steerer tube. Re-torque steerer clamp bolts to the specified torque (typically 5 Nm).

Pros and Cons

Pros

  • Significantly increases torsional stiffness for precise steering.
  • Lightweight construction without sacrificing durability.
  • Improves cockpit integration and aesthetics.
  • Secure and consistent clamping for both handlebar and steerer tube.
  • Premium finish and corrosion-resistant hardware for longevity.

Cons

  • Requires a 31.8mm diameter handlebar; not compatible with other sizes.
  • As a premium component, it may be priced higher than standard stems.
  • Availability of specific lengths may vary.

Setup, Compatibility & Care

Setup:

  1. Ensure you have a 31.8mm diameter handlebar.
  2. Clean the steerer tube and stem's steerer clamp surfaces.
  3. Apply a thin layer of carbon assembly paste if using a carbon steerer tube or handlebar.
  4. Install the stem onto the steerer tube, ensuring it is properly seated. Torque the steerer clamp bolts to the manufacturer's recommended specification (typically 5 Nm).
  5. Mount the handlebar into the stem's faceplate. Ensure the handlebar is centered. Hand-tighten the faceplate bolts.
  6. Gradually tighten the faceplate bolts in a crossing pattern to ensure even pressure. Torque to the manufacturer's recommended specification (typically 5 Nm).
  7. Align the handlebars with the front wheel and then torque the stem's steerer clamp bolts fully.

Compatibility:

  • Handlebar Clamp Diameter: 31.8mm
  • Steerer Tube Diameter: Standard 1 1/8"
  • Frame Integration: Designed for modern mountain bike frames and head tube designs.

Care:

  • Regularly clean the stem with mild soap and water, using a soft cloth.
  • Inspect all bolts for tightness and signs of wear before each ride.
  • Periodically re-torque bolts to ensure secure clamping, especially after initial installation or significant impacts.
  • Avoid using abrasive cleaners or solvents, which can damage the finish.
