Uncompromising Grade 5 Metallurgy: Strength & Agility

Crafted from premium S-Grade TC4 (Grade 5) titanium alloy, this lockring boasts exceptional high tensile strength for professional-grade quality and long-term durability. Delivering a perfect blend of structural strength and nimble agility, it is significantly harder, stronger, and completely feather-light compared to traditional stock options. Titanium is naturally rust and corrosion-proof, ensuring the lockring threads remain completely immune to wet weather, road mud, and harsh environmental exposure.

Rotational Weight Reduction

At an incredibly lightweight 8.05g, the S-PARTS lockring cuts nearly half the weight of a standard steel equivalent. Stripping away weight at the hub profile lowers the wheelset’s rotational mass, providing competitive cyclists with a noticeable edge through quicker acceleration and sharper climbing responsiveness.

Vacuum Nitriding & PVD Aesthetic Variety

S-PARTS elevates your hub interface through advanced surface engineering. Enhanced with a state-of-the-art vacuum nitriding and anodising treatment, the lockring surface shines significantly brighter and smoother, easily surpassing traditional electroplating processes. This polished surface reflects superior craftsmanship and provides a vibrant, long-lasting finish that highly resists wear. Available in multiple colours, it allows you to customise and add a touch of personalisation to your bike’s style.

Elite Wheelset Compatibility

Designed to handle high stress, this external-spline lockring provides a seamless, secure fit for premium open-market centre lock hubs and top-tier disc wheelsets.
