The Shimano 105 CN-5700 Chain isn't just any old bicycle drive chain. This ultra-narrow, 10-speed specific chain has chromed link pins and heat-treated rollers, pins, and plates for optimum durability, as well as an asymmetrical profile designed to shift better on the front rings and the cassette. Since the action of climbing up the ramps and pins from one chainring to another is slightly different from climbing up one cog to the next, Shimano chose to shape the left and right side plates differently to optimize the chain for each specific purpose. Shimano also designed the outer plate to reduce the instance of chain suck. The result is a chain that works in harmony with their 10-speed systems to provide a shift quality unrivaled by any of their previous efforts. The Shimano 105 CN-5700 Chain is designed for use with 10-speed drivetrains only.
