Aerospace Grade Titanium Headset Spacers

Product Introduction 

Aerospace Grade Titanium Headset Spacers are precision-machined hollow cylindrical components designed to adjust stem height on high-performance bicycle steering assemblies. They are made of Ti-6Al-4V (Grade 5) titanium alloy which has a tensile strength of 895-1000 MPa with a density of just 4.43 g/cm3. Surface polish is Ra ≤ 1.6 µm to provide constant bearing preload. Manufacturer of these spacers is Baoji Huacan, 40+ CNC machines, 10+ years of titanium machining expertise, complete OEM/ODM support. Whether you need conventional dimensions or bespoke parts from a design, we can provide precise parts to your specifications.

Why Choose Us

Getting the appropriate headset spacer is more important than most riders think. What makes our titanium spacers special is this.

Best Power to Weight Ratio

Ti-6Al-4V is up to 3 times stronger than 6061-T6 aluminium with a tensile strength of up to 1000 MPa and is yet much lighter than steel. Your cockpit remains tight without additional weight.

Galvanic Corrosion No

Aluminium spacers may freeze on carbon steerer tubes because to sweat and electrolyte ingress. Our titanium spacers provide a passive TiO₂ oxide layer, making them chemically resistant to road salts, perspiration and moisture.

No Smash No Break

High stem clamp torque may cause delamination of carbon fibre spacers. Titanium retains its form and maintains the bearing preload under impact and compression pressures.

Heat Stability

The low coefficient of thermal expansion means your headset preload remains constant, whether you're riding icy alpine descents or scorching heat.

Manufacturing Capability

Baoji Huacan operates 40+ advanced CNC machines including lathes, machining centers, and gantry systems. Annual production capacity exceeds 1,000 tons of finished titanium parts.

Our melting capability partners support VAR and PAM processes with annual ingot capacity exceeding 5,000 tons. Forging capacity exceeds 3,000 tons per year using equipment including a 4,000-ton hydraulic press.

FAQ

Q: What titanium grade do you use for headset spacers?

A：Standard production uses Ti-6Al-4V (Grade 5). Grade 2, Grade 9, and Grade 23 are also available depending on your application.

Q: Can you produce spacers to my custom dimensions?

A：Yes. We manufacture fully according to customer drawings or 3D models. There are no fixed standard sizes — everything is customizable.

Q: What is the minimum order quantity?

A：We support prototypes, small batches, and large-volume production. Contact us to discuss your specific quantity requirements.

Q: What surface finishes are available?

A：Options include machined natural finish, anodizing (multiple colors), polishing, bead blasting, and pickling. Custom finishes are available on request.

Q: How do I get a quote?

A：Send your drawings, specifications, and quantity to sherry@hc-titanium.com. Our team will respond promptly with pricing and lead time.

Q: Are these spacers compatible with carbon steerer tubes?

A：Yes. Titanium's inert surface eliminates the galvanic corrosion risk that causes aluminum spacers to seize on carbon steerers, making it an ideal choice for mixed-material cockpits.
