In order to ensure flawless and reliable functionality even with oversized sprocket sets, the precision of shifting and shifting has gone through the design of a 12-speed chain that has necessarily been the subject of a lot of research and development energy to make it just as reliable and durable as compared to to an 11-speed chain, despite the reduction in thickness compared to the latter. The new 12-speed Chorus groupset benefits from a new Chorus 12 chain that ensures the same reliability and performance as the Super Record level one, weighing just 241 grams for 110 links.

• Width from 5.15 mm.
• Faster shifting and lightness.
• Very high performance and durability over time.
• Pegs aligned with the external surface.
• Smoothness and precision.
• Wear resistance unchanged.
• The chain drops in weight and thins but as hard as the 11-speed model.
• Optimized design.
• Optimal operation in harmony with the tooth pattern of the pinions and crowns.
• Ultra-link system.
• High-level smoothness and reduction of dispersions.
