Incorrect selection may result in failure to install or damage to components due to improper installation.Core Material Advantages (vs. Aluminum Alloy & Steel Freehub Bodies)High Strength & Resistance to Bite/Indentation: Tensile strength is far superior to 7075 aluminum alloy. Under high‑power climbing or e‑bike aggressive pedaling, it effectively resists spline indentation and cassette seizure, eliminating the common problem of aluminum freehub bodies wearing out and developing bite marks over long‑term use.Lightweight: Weight is close to that of aluminum freehub bodies and significantly lighter than steel, reducing wheel rotational inertia for quicker startup and sprint response.Corrosion & Rust Resistance: Titanium naturally resists rain, mud, and salt spray corrosion. In wet, rainy, or off‑road conditions, it does not easily rust or seize, ensuring greater long‑term stability.High Rigidity & Low Deformation: Under high torque, dimensional changes are minimal. Power transfer is direct with tighter engagement, eliminating pedal play and providing crisper power delivery.Installation & Assembly PrecautionsDo not hammer the cassette into place.Tightening the cassette lockring must be done using a dedicated cassette tool and a torque wrench, following the manufacturer's specified torque. Never use a hammer to force the cassette onto the freehub – doing so will easily damage the external splines, causing deformation or stripping.Prevent Galvanic Corrosion Between Dissimilar MetalsWhen a titanium freehub is used with a steel cassette and steel spacers, prolonged contact may cause galvanic corrosion. Apply a thin coat of anti‑seize assembly paste on the contact surfaces to prevent long‑term sticking or seizing.Ensure Correct Specifications – Do Not Force AssemblyConfirm that the freehub type (HG / Micro‑Spline / XDR) and speed rating match your cassette. Different spline dimensions are not interchangeable; forcing an incompatible cassette will directly damage the spline teeth. When adding shifting spacers, ensure they sit flat and flush – do not allow them to tilt or bind.Bearing Installation – No Over‑Press or Off‑Center PressureWhen replacing the freehub’s internal bearings, use a bearing press tool to apply even, coaxial pressure. Hammering on one side or applying angled force will deform the freehub’s inner bore and cause bearing noise or premature failure.
