A compact design, advanced technologies, and carefully selected materials combine to ensure outstanding performance in all conditions.\u003c\/strong\u003e \u003c\/p\u003e\u003cp\u003eThe fully redesigned cage enables compatibility with cassettes up to 48 \r\nteeth, expanding capability for off-road riding.\r\nExtended range, fast charging, and smart connectivity complete a system \r\nspecifically engineered for gravel, meeting the needs of the most \r\ndemanding riders.\u003c\/p\u003e\u003cp\u003eOne of the most significant developments of the 13 platform, for both\r\n Record and Super Record 13, is its gravel-specific evolution: the \"X\" \r\nrear derailleur.\r\nBuilt on the same technical architecture as the Super Record 2x13 \r\nderailleur, it redefines shifting performance even on the roughest \r\nterrain. Thanks to an optimised derailleur path, it delivers smooth, \r\nfast, and immediate gear transitions, even under high pressure on the \r\npedals, maximising efficiency across the entire cassette range.\u003c\/p\u003e\u003cp\u003eThe key distinguishing feature compared to the road version is the \u003cstrong\u003eNano Clutch\u003c\/strong\u003e,\r\n a miniaturised clutch that maintains optimal chain tension on uneven \r\nterrain and rough descents, preventing chain drops from the front \r\nchainring and ensuring maximum stability.\r\nCombined with the dedicated 1x chainring tooth profile, the Nano Clutch \r\nforms a system specifically engineered to minimise chain drops even in \r\nthe most demanding conditions.\r\nThe architecture, with the rear derailleur positioned beneath the \r\ncassette, delivers a cleaner aesthetic, improved aerodynamics, and \r\nperfect alignment between pulleys and gear ratios. The result is \r\nquieter, more precise, and more reliable shifting.\u003c\/p\u003e\u003cp\u003eDespite similar size and weight to the road version, Record X offers \r\ncategory-leading impact resistance and cage stiffness.\r\nEfficiency is further enhanced by two differentiated pulleys: the upper \r\n12-tooth eccentric pulley maintains optimal chain distance even with \r\nlarge cassettes, while the oversized 16-tooth lower pulley improves \r\nchain engagement and smoothness. Both feature a profile designed to \r\nguide each link precisely, ensuring continuous and efficient chain flow.\r\nAnother key feature is the cage geometry, with an extended body cage \r\ncompatible with cassettes up to 48 teeth, ideal for tackling the \r\nsteepest climbs. The crankset has also been optimised for gravel use, \r\nretaining Ultra-Torque technology with a 47.5mm chainline,  perfect for \r\nmodern frames and increased tyre clearance.\u003c\/p\u003e\u003cp\u003eThe derailleur \r\nfeatures a universal mounting design, compatible with both UDH \r\n(Universal Derailleur Hanger) and traditional hangers. It is powered by a\r\n removable battery with a range of up to 750km and ultra-fast charging: \r\njust 60 minutes are needed to reach full capacity. Battery status can be\r\n easily monitored via the integrated LED, the MyCampy app, or compatible\r\n cycle computers. The USB-C connector ensures full compatibility with \r\nmodern devices, including smartphones that can be used as power banks in\r\n emergency situations.\r\nThe charging system and cable are shared across the entire 13 platforms.\u003c\/p\u003e\u003cp\u003eThe\r\n design also reflects Campagnolo's excellence: the front section of the \r\ncage is made of carbon with a direct-from-mould finish, while anodised aluminium components with tone-on-tone details  and the  refined branding\r\n highlight the brand’s attention to detail.\r\nThe result is smooth, fast, precise, and silent shifting even in the \r\nmost extreme conditions. Additionally, thanks to compatibility with road\r\n 1x cranksets featuring a 45.8mm chainline, the X derailleur enables \r\nsingle-chainring road setups with one of the widest gear ranges \r\navailable on the market.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eWeight: 342g (Without battery)\u003c\/li\u003e\n\u003cli\u003eMax Cassette: 48T\u003c\/li\u003e\n\u003cli\u003eClutch: Nano\u003c\/li\u003e\n\u003cli\u003eBattery life: Up to 750km\u003c\/li\u003e\n\u003cli\u003eCharge time: 60 minutes\u003c\/li\u003e\n\u003cli\u003eMounting: UDH\/ Traditional hanger\u003c\/li\u003e\n\u003cli\u003ePlatform: Record \/ Super Record X 13x\u003c\/li\u003e\n\u003c\/ul\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecise, smooth, efficient, and reliable shifting\u003c\/strong\u003e: Perfect performance in all riding conditions\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRedesigned derailleur positioning:\u003c\/strong\u003e Improves aerodynamics while ensuring optimal alignment with the cassette\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNano Clutch technology:\u003c\/strong\u003e A miniaturised clutch system that guides the chain through every pedal stroke, maintaining ideal tension and preventing chain drops\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePulley system\u003c\/strong\u003e: Engineered to accommodate cassettes up to 48 teeth, delivering outstanding performance on steep climbs and rough terrain\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eUDH and traditional derailleur hangers are compatible\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnLock System:\u003c\/strong\u003e a manual release mechanism that allows the derailleur to be repositioned manually in case of system malfunction\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRefined design\u003c\/strong\u003e: Down to the smallest detail, featuring carbon and aluminium components with branding integrated directly into the manufacturing process\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRemovable battery:\u003c\/strong\u003e Easily rechargeable via magnetic quick-snap ports, shared across the entire Platform 13 range\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated position sensor:\u003c\/strong\u003e the derailleur automatically adjusts to maintain optimal alignment with the selected sprocket at all times\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Campagnolo","offers":[{"title":"Default Title","offer_id":57918316773708,"sku":"CPB1002X","price":410.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1041\/5715\/1564\/files\/cpb1002x.jpg?v=1782668373","url":"https:\/\/eatcycling.co.uk\/products\/record-x-wireless-13x-rear-derailleur","provider":"EAT Cycling","version":"1.0","type":"link"}
