Campagnolo's Super Record Wireless 12-speed chain is not only suitable for any Campagnolo rim or disc brake 12-speed groupset, but it also offers one of smoothest and precise shifting performances available. In order to guarantee impeccable, reliable performance (even with the new wider cassette ratios) plus precision shifting by the front and rear derailleurs, the design of this 12 speed chain has entailed a tremendous amount of research and development by Campagnolo's R&D Engineers. The 12-speed chain needed to be as reliable and long-lasting as the 11-speed chain, despite being narrower. This is the lightest chain in the Campagnolo range, with no reduction in durability, efficiency or performance compared to its 11-speed counterpart. It fact its wear resistance is unsurpassed, putting it at the pinnacle of the Campagnolo chain range. The ultra link system makes the chain safe and longer lasting. The chain comes with two fastening options, the Classic Campagnolo pin or the C Link for even simpler removal and cleaning. The two versions were conceived to deliver the versatility needed to satisfy the different requirements for all kinds of use. Both versions offer the same resistance and efficiency.
