Product Information
Full details
The Renthal Stem Top Cap Kit in Black is designed for cyclists seeking a premium, unified look for their bike's cockpit, specifically complementing the V2 Apex stem. Its key benefit is the seamless aesthetic integration and lightweight strength. A potential caveat is that its design is highly specific to the V2 Apex stem, limiting broader compatibility for a truly unified look with other stem models. This kit offers CNC-machined precision, durable anodizing, and includes various headset spacers for stack height adjustment.

FAQs
What size steerer tube is this kit compatible with?
The headset spacers are designed for standard 1 1/8" steerer tubes. The top cap and bolt are specifically styled to match the Renthal V2 Apex stem.
Can I use this top cap with a stem other than the Renthal V2 Apex?
While the spacers will fit any 1 1/8" steerer tube, the top cap's aesthetic (chamfers and surface finish) is specifically designed to match the Renthal V2 Apex stem. It may not look perfectly integrated with other stem models.
What is the total weight of the kit?
The total weight is approximately 27 grams, depending on the spacers used.
How do I clean the anodised finish?
Use a soft cloth with mild soap and water. Avoid abrasive cleaners or solvents to preserve the anodised finish.
What are the included spacer sizes?
The kit includes 2.5mm, 5mm, 10mm, and 20mm headset spacers.
What tool is needed to install the top cap bolt?
A 6mm hex wrench is required for the installation and adjustment of the top cap bolt.
Does this kit come in other colors?
The product description specifies a black finish. Please refer to retailer information for any other available color options.
Troubleshooting
Top cap bolt does not tighten or feels stripped
Ensure you are using the correct 6mm hex wrench and that the bolt is properly seated in the hex interface. Check if the star nut or compression plug in the steerer tube is damaged or cross-threaded. If damaged, it may need replacement.
Headset feels loose after installation
The top cap's primary role is to preload the headset bearings. Ensure the stem bolts are loosened, then tighten the top cap bolt just enough to remove headset play. Re-align the stem and torque the stem bolts to the manufacturer's recommended specification.
Spacers do not fit on the steerer tube
Verify that your bicycle steerer tube is a standard 1 1/8" diameter. Ensure the spacers are not obstructed by any cables or housing routed internally.

Setup, Compatibility & Care Instructions
Compatibility:
This top cap kit is specifically designed to complement the Renthal V2 Apex stem. While the headset spacers are universal for 1 1/8" steerers, the top cap and bolt aesthetic is optimized for the V2 Apex. Ensure your bicycle uses a standard 1 1/8" steerer tube for the spacers to fit correctly.
Setup:
- Ensure your steerer tube is clean and free of debris.
- Select the desired headset spacers and stack them onto the steerer tube above the headset upper bearing.
- Place the Renthal top cap over the spacers.
- Insert the top cap bolt through the top cap and into the steerer tube's star nut or compression plug.
- Tighten the top cap bolt using a 6mm hex wrench. Important: Do not overtighten. The initial tightening should remove play in the headset bearings. After the stem is mounted and aligned, torque the stem bolts to the manufacturer's specification.
Care:
Clean the top cap kit regularly with mild soap and water using a soft cloth. Avoid abrasive cleaners or solvents, which can damage the anodised finish. Periodically check the top cap bolt for tightness.
