Campagnolo: SUPER RECORD 12 SPEED CHAINNew Super Record™ 12 Speed chain: slim, robust, smooth and precise.The chain, in all its apparent simplicity, plays a critical role in the cyclists 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.Weight 220 gr./110 links FEATURES & BENEFITSWidth 5.15 mmFaster shifting and lighter weightExtremely high, long-lasting performancePins aligned to the outer surfaceSmoothness and precisionUnsurpassed wear resistanceThe chain is lighter and thinner, but lasts just as long as the previous model.Optimized designOptimal working in harmony with the sprocket and chainring tooth designs.Ultra-link systemHigh level smoothness and reduced losses.
