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.
Technologies
- 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.
Features and Benefits
- Width from 5.15mm
- Faster lighter shifting
- Extremely high performance levels and durability over time
- Pins aligned with the external surface: Smoothness and precision
- Unchanged resistance to wear and tear: A lighter, narrower chain than the 11-speed, but just as durable.
- Optimised design: Optimum performance in line with the design of the teeth on the sprockets and crowns.
- Ultra-link System: Top-level smoothness and less dispersion.
- Weight: only 241g (110 links)
