GOLDIX Titanium Alloy Hub Freehub Body MTB HG XD MS Road HGR XDR MSR Compatible with Most GOLDIX Hub Models Lightweight Durable

Brand: GOLDIXProduct Name: Titanium Alloy Freehub BodyMaterial: Titanium AlloyManufacturing Process: CNC MachinedBearings: TPI 6802 (2 pcs)Freehub Types: MTB (HG, XD, MS) / Road (HG-R, XDR, MS-R)Important Note: HG and XD are for MTB use; HG-R, XDR, and MS-R are for Road use.Please carefully verify your cassette model before purchasing; incorrect selection may result in installation failure or component damage due to improper fitting.Core Material Advantages (vs. Aluminum and Steel Freehubs)High Strength & Bite Resistance: Tensile strength far exceeds that of 7075 aluminum alloy. It resists spline indentation and cassette seizure during high-power climbing or aggressive pedaling (including e-bikes), solving the common issue of aluminum freehubs becoming unusable due to deep gouging/notching over time.Lightweight: Weight is comparable to aluminum freehubs and lighter than steel ones; reduces rotational inertia for faster acceleration and sprinting response.Corrosion & Rust Resistance: Titanium naturally resists corrosion from rain, mud, and salt spray; it remains stable and resists rusting or seizing in humid, wet, or off-road conditions.High Rigidity & Minimal Deformation: Low deformation under high torque ensures direct power transfer and tighter engagement tolerances; eliminates "play" in the drivetrain for crisp, efficient power delivery.Installation PrecautionsDo not use excessive force or hammering when installing the cassette.Always use a dedicated cassette tool and a torque wrench to tighten the lockring to manufacturer specifications; hammering the cassette to force it on can easily damage the freehub splines, causing deformation or stripped threads.Dissimilar Metal Contact (Galvanic Corrosion Prevention)Long-term contact between a titanium freehub and steel cassettes or spacers can lead to galvanic corrosion; apply a thin layer of anti-seize grease to contact surfaces to prevent the parts from seizing or bonding together over time. Specifications must match; do not force assembly.Verify the freehub body type (HG, Micro Spline, or XDR) and ensure the speed compatibility matches the cassette. Spline dimensions vary by specification; forcing a mismatch can cause the spline teeth to shatter. When installing drivetrain spacers, ensure they sit flat and flush; do not allow them to become tilted or pinched.Avoid excessive or uneven pressure during bearing assembly.When replacing internal freehub bearings, use a bearing press tool to apply force evenly. Striking one side or hitting at an angle can deform the freehub bore, causing bearing noise and rendering the unit unusable.
