X Rear Derailleur: Entirely Dedicated to Gravel Riding
This rear derailleur is the most obvious example of the gravel-oriented approach of the Super Record. Developed from the technological foundation of the Road version, the Super Record X rear derailleur features a number of new technical solutions specifically designed for gravel riding.
First and foremost, it features the new Nano Clutch, a miniaturized clutch designed to maintain proper chain tension on rough trails and bumpy descents and prevent the chain from falling off the front chainring. Furthermore, the entire design has been recalibrated for off-road cycling. To prevent impacts and vibrations, the assembly area has been reinforced and the carbon cage has been extended to 92.5 mm to operate with cassettes of up to 48 teeth.
Despite its size and weight, very similar to the purely road version, this rear derailleur features class-leading impact resistance and flexural rigidity of the cage.
The derailleur’s efficiency is also ensured by the two pulleys with different diameters and positions: the upper, 12-tooth guide pulley operates eccentrically, on a rotation axis set back from the cage so as to maintain the correct distance even on large teeth. The lower tension pulley is a 16-tooth oversized version to facilitate smooth chain movement at the system’s entry point. Both pulleys have differentiated tooth profiles, designed to accommodate each individual chain link for perfect glide. This shows Campagnolo’s typical attention to even the smallest detail. The result is smooth, fast, precise, and silent shifting, even in the most extreme conditions.
The Super Record X rear derailleur is designed with a universal mount, compatible with any frame, both with the UDH (Universal Derailleur Hanger) system and with traditional hangers. The removable battery ensures a range of up to 750 km and is easy to charge thanks to the quick-snap magnetic ports and Campagnolo charging cable.
The aesthetics also reflect the Campagnolo identity: carbon with a direct mold finish for the inner cage and front end, laser-engraved and anodized aluminum for an elegant look even for a technical component.
Within the platform, the X Rear Derailleur can also be paired with the 1x road crankset, thus for configurations with a 45.8 mm road chain line, creating a single-chainring road bike with the widest range of gear ratios on the market.
