In order to guarantee impeccable, reliable performance even with bigger cassettes, precision shifting by 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 an 11-speed chain, despite being narrower than the latter. The new 12-speed Chorus groupset benefits from a new Chorus 12 chain that ensures the same reliability and the same performance levels as that of the Super Record category, its 110 links weighing only 241 grams.
Width from 5.15 mm for 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.
Optimized design for optimum performance with the 12 speed cassette.
Optimum performance in line with the design of the teeth on the sprockets and crowns
Ultra-link System creating top-level smoothness and less dispersion.
Chain Weight - 243 grams (110 links)
