In order to guarantee impeccable, reliable performance even with the new wider cassette ratios, precision shifting by the front and rear derailleurs has seen design of a 12 speed chain entailing huge research and development efforts to make it as reliable and long-lasting as the 11 speed chain, despite being narrower.
The new 12 speed Chorus groupset benefits from a new 12 speed chain that ensures the same reliability and performance levels as that of the Super Record.
Ultra-link connecting system
Constant, extremely high performance levels over time
5.15mm wide, the narrowest chain ever produced: maximum smoothness and precision when shifting.
The external part of the link is perfectly smooth.
