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.
