To ensure flawless and reliable functionality even with oversized sprocket cassettes, shifting and derailleur precision has been achieved through the design of a 12-speed chain that has necessarily undergone extensive research and development efforts to make it as reliable and durable as an 11-speed chain, despite the reduced thickness compared to the latter. The new 12-speed Chorus groupset benefits from a new Chorus 12 chain that guarantees the same reliability and performance as the Super Record level chain.

Features:

• Width of 5.15 mm: faster shifting and lightweight
• High performance and long-lasting durability
• Pins aligned with the outer surface: smoothness and precision
• Unchanged wear resistance: the chain is lighter and thinner but lasts as long as the 11-speed model
• Optimized design: optimal operation in harmony with the tooth profiles of sprockets and chainrings
• Ultra-link system: high-level smoothness and reduced friction losses
