Product Information

Full details

The Renthal Apex V2 Stem is designed for performance-focused mountain bikers seeking enhanced cockpit control and a cleaner front-end integration. Its key benefit lies in significantly increased torsional stiffness for more direct steering, though its premium construction may come at a higher price point. This stem combines forged and CNC-machined aluminum with a wide body and refined clamp designs for durability, reduced weight, and superior handling on challenging terrain.

Extended Product Information

FAQs

What is the main benefit of the Apex V2 stem's wide body?

The 56mm wide stem body significantly increases torsional stiffness, leading to more direct steering input and improved control, especially under heavy load or on rough terrain.

Is this stem compatible with carbon handlebars?

Yes, it is compatible with most 31.8mm clamp diameter handlebars, including carbon ones. For carbon handlebars, it is recommended to use a carbon assembly paste and follow the torque specifications carefully to prevent damage.

What lengths are available for the Renthal Apex V2 Stem?

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

How does the internal machining help?

Extensive internal machining removes material from non-critical areas, reducing the overall weight of the stem without compromising its strength or durability. This contributes to a lighter and more responsive front end.

What material is the stem made from?

The main stem body is constructed from 2014 aluminum, while the faceplate is made from higher-grade 7050 aluminum for enhanced clamping durability.

How do I maintain the stem?

Clean the stem with mild soap and water. Periodically check that all bolts are securely tightened to the manufacturer's recommended torque values. Inspect for any signs of wear or damage.

Does the stem come with bolts?

Yes, the stem includes black-plated stainless steel hardware, which is corrosion-resistant and ensures consistent clamping force.

Troubleshooting

Handlebar slips or moves

Ensure the handlebar faceplate bolts are tightened evenly and to the correct torque specification. Clean both the handlebar and stem clamp surfaces to remove any grease or dirt.

Stem creaks or makes noise

Check that all bolts (steerer clamp and faceplate) are torqued correctly. Apply a thin layer of carbon paste if using carbon handlebars, or a light grease on alloy bars and stem surfaces. Ensure no debris is caught between the stem and handlebar/steerer.

Difficulty fitting handlebar

Confirm the handlebar has the correct 31.8mm clamp diameter. Ensure the handlebar is not bent and that the stem faceplate is correctly aligned.

Pros and Cons

Pros

  • Significantly increased torsional stiffness for precise steering.
  • Durable construction through forging and CNC machining.
  • Reduced front-end weight due to extensive internal machining.
  • Secure and consistent handlebar clamping.
  • Clean aesthetic and improved frame integration.

Cons

  • Premium construction may result in a higher cost.
  • Requires specific handlebar clamp diameter (31.8mm).
  • Multiple length options might require careful selection.

Setup, Compatibility & Care

Setup:

  1. Ensure your handlebar has a 31.8mm clamp diameter.
  2. Verify the stem length (31mm, 40mm, or 50mm) suits your preferred riding position.
  3. Clean the steerer tube and inside of the stem clamp surfaces.
  4. Loosely install the stem onto the steerer tube, ensuring it is straight.
  5. Position your handlebar in the stem's 260° clamp and loosely install the faceplate bolts.
  6. Tighten the steerer clamp bolts to the manufacturer's recommended torque specification.
  7. Tighten the handlebar faceplate bolts incrementally and evenly to the manufacturer's recommended torque specification, following a star pattern.

Compatibility:

  • Designed for mountain bikes with a standard 1 1/8" (28.6mm) or 1.5" tapered steerer tube (ensure correct headset/reducer if applicable).
  • Compatible with handlebars featuring a 31.8mm clamp diameter.

Care:

  • Clean the stem regularly with mild soap and water, and a soft cloth. Avoid abrasive cleaners.
  • Periodically check all bolts for tightness and re-torque to specification if necessary.
  • Inspect for any signs of damage or wear, especially around the clamp areas.
