Shimano Ultegra CN-6600 10 Speed Triple Chain

DRIVETRAIN PERFORMANCE STARTS WITH THE CHAIN. THE SHIMANO ULTEGRA CN-6600 IS THE FACTORY-SPECIFIED 10-SPEED CHAIN FOR THE ULTEGRA 6600 GENERATION GROUPSET - ENGINEERED TO DELIVER FAST, PRECISE SHIFTING, LONG-TERM WEAR RESISTANCE, AND CONSISTENT POWER TRANSFER ON EVERY RIDE. WHETHER YOU'RE REPLACING A WORN CHAIN ON YOUR CURRENT BUILD OR MAINTAINING A TRUSTED ROAD BIKE, THE CN-6600 IS THE CORRECT, RELIABLE CHOICE FOR ANY SHIMANO 10-SPEED ROAD DRIVETRAIN.


KEY FEATURES

HyperGlide 10-Speed Optimisation - The CN-6600 is built around Shimano's HyperGlide chain technology, specifically optimised for HG sprockets to deliver fast and precise rear shifting performance - particularly during downshifts under load. Every link is engineered to work in harmony with Shimano's 10-speed cassette and chainring profiles for consistent, reliable gear changes at any cadence.
Chromised Rivet Pins for Wear Resistance - Chromised rivet pins harden the contact surfaces where wear accumulates fastest, extending chain service life and maintaining shifting accuracy for longer between replacements. A longer-lasting chain means less frequent drivetrain wear on your cassette and chainrings - saving money over the long term.
Zinc-Alloy Plated Outer Links - The zinc-alloy plated outer link surface treatment provides corrosion resistance and a clean silver finish that holds up to Queensland's humidity and coastal riding conditions. The treatment also helps chain lubricant adhere more consistently to the outer plates for improved lubrication retention between applications.
Directional HG-X Construction - The CN-6600 uses directional chain construction designed to work in a specific orientation, ensuring the chain engages cleanly with HG-compatible sprockets across the full cassette range - from the smallest sprocket in a sprint to the largest on a long climb.
Compatible with Ultegra 6703 and 105 5703 Triple - Shimano specifically recommends the CN-6600 for use with Ultegra 6703 and 105 5703 triple crankset configurations, making it the correct chain choice for both double and triple 10-speed road setups across the 6600 and 5600 groupset generations.
116 Links - Standard Road Length - Ships at 116 links, the standard length for road bike installation. Allows correct sizing for the full range of road bike frame geometries and drivetrain configurations. Note: a Shimano 10-speed connecting pin is required for installation and is not included.


WHY CHOOSE THE SHIMANO CN-6600?

When it comes to chain replacement, fitting the manufacturer-specified chain for your groupset generation is always the right decision. The CN-6600 is the OEM-specification chain for the Ultegra 6600 platform - meaning it's designed, profiled, and toleranced to work exactly with the sprockets and chainrings it was built alongside. For Brisbane riders maintaining a 10-speed Shimano road build, this is the chain that preserves your drivetrain's shifting performance and protects the long-term life of your cassette and chainrings.
