Product Information

Full details

The Wolf Tooth Ultralight Stem Cap and Bolt is an ideal upgrade for weight-conscious cyclists looking to refine their bike cockpit with a sleek, minimalist aesthetic. Precision-machined from high-grade 7075-T6 aluminum, this component significantly reduces rotating and static weight compared to standard steel hardware; however, users must ensure their bike utilizes a standard 1 1/8 inch steerer tube to guarantee a proper fit.

Extended Product Information

FAQs

Will this fit a 1-inch steerer tube?

No, this stem cap is specifically designed for 1 1/8 inch steerer tubes only.

Does it come with a star nut?

No, this product includes only the stem cap and the matching alloy bolt.

Can I use my existing steel bolt?

While it may fit, it is recommended to use the provided alloy bolt to maintain the weight savings and intended flush aesthetic.

What is 7075-T6 aluminum?

It is a high-strength aluminum alloy used in aerospace applications, chosen here for its excellent strength-to-weight ratio.

How much does the setup weigh?

The total assembly weighs 8 grams.

Troubleshooting

Bolt feels difficult to thread

Ensure the star nut or compression plug in your steerer tube is properly aligned and clean the bolt threads of any debris.

Cap is not sitting flush

Check to ensure the steerer tube is cut at the correct length, typically 2-3mm below the top of the stem or spacer stack.

Pros and Cons

Pros

  • Significantly lighter than stock steel alternatives
  • Durable 7075-T6 aluminum construction
  • Sits flush for a clean, low-profile aesthetic
  • Simple installation process

Cons

  • Compatible only with 1 1/8 inch steerer tubes
  • Requires careful torque management to avoid stripping alloy threads
  • Cannot be used as a structural replacement for non-standard headset compression systems

Setup, Compatibility & Care

To install, simply remove your existing stem cap and bolt. Ensure the steerer tube is standard 1 1/8 inch diameter. Place the Wolf Tooth cap onto the steerer tube or spacer, then insert and tighten the provided alloy bolt. Because the bolt is made of alloy, use a torque wrench to avoid over-tightening. For care, wipe occasionally with a soft cloth. When performing deep cleans, avoid harsh chemical degreasers that may dull the anodized finish.
