Campagnolo Super Record X 13 WRL Rear Derailleur with Nano Clutch - 13-Speed, Wireless, Long Cage, Standard Mount, w/o Battery, Black

One of the most significant developments of the Super Record 13 platform is this Super Record X rear derailleur dedicated to gravel riding~The most distinctive feature compared to the road model is the new "Nano Clutch", a miniaturized clutch that maintains the right chain tension on rough terrain and bumpy descents, preventing the chain from falling off the front chainring and ensuring absolute stability. Another key feature is the new carbon cage geometry extended to 92.5 mm, compatible with cassettes up to 48 teeth and ideal for tackling the steepest climbs. The result is smooth, fast, precise, and silent shifting, even in the most extreme conditions. Furthermore, thanks to its compatibility with the 1x road crankset with a 45.8 mm chain line, the X Rear Derailleur allows single-chainring road bikes to be configured with the widest range of gear ratios available on the market.
