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.

New Super Record™ 12 Speed chain: slim, robust, smooth and precise. The chain, in all its apparent simplicity, plays a critical role in the cyclist's safety and in optimizing the entire transmission mechanism. The new Super Record™ 12 Speed chain also had to be redesigned from scratch to work with all the other new transmission components. Therefore, the first and most important objective was reducing its overall dimensions. Its width is now 5.15 millimetres, thanks to the new pins which are perfectly aligned with the links’ outer surfaces. The second objective was safeguarding its performance. This was achieved thanks to the Ultra-link system that makes the chain safe and durable, and a special treatment that guarantees extreme smoothness and precision shifting.

Blackspire Stinger tensions any chain in the most challenging circumstances. On rough terrain a chain on the small chain ring can jump of the gear. Stinger guarantees optimal chain tension at all times. It will never lose his chain. It is CNC milled from lightweight 6061 T-6 aluminum and compatible with chain rings up to 40 teeth. The Stinger is available for mounting on three standard mounting modes: BB mount, ISCG and ISCG'05. More information about these mounting standards can be found in downloads. Furthermore, this chain tensioner is also available for mounting with E-type front derailleurs.
