The chain, in its apparent simplicity, plays a critical and fundamental role for the safety of the cyclist and for optimizing the entire transmission mechanism. The new Super Record chain also had to be redesigned to interface with all the other new components of the transmission. The first and fundamental objective was therefore to reduce its bulk. Now the width is 5.15 millimeters, thanks also to the new pins perfectly aligned with the outer surface of the links. The second objective was to safeguard its performance thanks to the Ultra-link system that provides safety and durability to the chain and a special treatment that ensures extremely high smoothness and precision in shifting.
