1, Each part is designed and manufactured with close combination, the accuracy of parts is controlled within lum, which improves the high-speed transmission performance of the chain and supports the chain to operate in the best state at every moment;
2. The inner and outer chain plate and pin shaft are hollow out design, which can effectively reduce the weight of the vehicle, and effectively improve the sediment discharge function of the chain, and extend the service life of the chain;
3. The surface of the pin shaft is hardened with mHV of more than 1600, which increases the anti-wear ability of the pin shaft surface and improves the durability of the chain;
4. The surface of the chain is coated twice, and finally the advanced technology of titanium nitride coating is adopted to improve the wear-resistant application function of the chain surface, so that the chain speed change is smoother and wear-resistant.
DOUBLE X-BRIDGE DESIGN
The Double X-Bridge design ensures smoother shifting by allowing the inner and outer chain plates to seamlessly interact. Both sides of the chain plates feature identical bridges and chamfers, eliminating the need for directional installation and increasing convenience. This design reduces noise and friction by minimizing tooth interference during shifting.
LIGHTWEIGHT DESIGN
The precisely engineered hollow structure of the inner and outer chain plates and pins reduces weight without compromising strength. The SUMC SL 116-link chain with quick-release weighs approximately 235g, outperforming the Shimano Dura-Ace 114-link chain at 251g. The hollow design also facilitates easier cleaning by allowing dirt to be expelled more efficiently, reducing shifting resistance.
WAIST GUIDE BEVELS
Asymmetrical guide bevels provide narrow spacing for rapid engagement, enhancing shifting smoothness and performance.
COLORFUL ELECTROPLATING
The colorful electroplating is stain-resistant, corrosion-resistant, and fade-resistant, reducing maintenance frequency and ensuring worry-free riding.
DURABILITY AND EFFICIENCY
The chain features strong tensile strength and does not break easily. Each chain is paired with a durable quick-release link that is easy to remove, clean, and reuse.
