Campagnolo's Chorus 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. The 12-speed Chorus groupset benefits from a new 12-speed chain that ensures the same reliability and performance levels as that of the Super Record, with constant, extremely high performance levels over time. **Technical Specifications:** * Suitable for any Campagnolo 12-speed rim or disc brake groupset * 114 Links, 5.15mm wide * Lighter and narrower than an 11-speed chain but just as durable and resistance to wear and tear * Ultra Link System for top-level fluidity, high strength chain connection, greater safety and longer chain life * Silver colour * External part of the links are perfectly smooth for optimum performance in line with the design of the teeth on the sprockets and crowns. * Advanced Nickel-PTFE anti-friction treatment, for reduced friction, smooth pedalling, quiet operation, greater efficiency and longer chain life * Pins aligned with the external surface: Smoothness and precision * Requires the Campagnolo Ultralink UT-CN400 Chain Tool for installation * Weight: 241g (based on 110 links)
