Top Features of the KMC X10-93 10 Speed Chain Features Enhanced Durability: With unique SP (StrechProof) treatment, the durability has been effectively enhanced by reducing the attrition between inner plates and pin. As a result, chain life has been significantly prolonged Pin Power: The unique KMC "Bulls-Eye" pin mushrooming technique, which provides 200kgf of average pin power for unsurpassed side plate retention X-Bridge: This is on the outer plate, configured with precisely articulated angles for quicker and smoother gear shifting and quieter riding. Lightweight shorter length pins length combine with high-grade materials to reduce weight. Tensile strength safety is assured with a minimum 1020kgf above ISO standards Noiseless: Special "Z" bridge side plate configuration and chamfering provide excellent shifting performance and minimize noise even with a mix of different derailleur components Nimble Shifting: The "Z" bridge side plate configuration means faster, smoother, quieter and more precise shifting Light Weight: Shorter pin length and use of higher grade materials are combined to reduce weight Tensile Strength: Safety, performance and peace of mind are assured, with minimum of 1020kgf above ISO standard X-SP Treatment: Special proprietary X-SP treatment is applied to both high alloy pins and plates to reduce the friction, thus, to enhance the chain life Lower Bridge: This lower bridge hastens the down gear shifting and yet mitigates the engaging impact between sprocket and chain Upper Bridge: The upper bridge forms a slant vault parallel to the tip of tooth movement. This vault shape makes the tooth and the chain engage much more precise and swifter Specification Size: 1/2" x 11/128" Pin length: 6.2mm Colour: Silver Speed: 10 Complete with missing link More details pls see picture.
