The KMC X-bridge configuration guarantees faster shifting and smoother riding.
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.
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
XSP Treatment: Special proprietary XSP 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.
