{"product_id":"campagnolo-record-x-rear-derailleur","title":"Campagnolo Record X Rear Derailleur","description":"\u003cp\u003e\u003cspan\u003eThe new Record X redefines gravel shifting, delivering unprecedented precision, speed, and silence even on the most demanding terrain. A compact design, advanced technologies, and carefully selected materials combine to ensure outstanding performance in all conditions. The fully redesigned cage enables compatibility with cassettes up to 48 teeth, expanding capability for off-road riding. Extended range, fast charging, and smart connectivity complete a system specifically engineered for gravel, meeting the needs of the most demanding riders.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cmeta charset=\"UTF-8\"\u003eOne of the most significant developments of the 13 platform, for both Record and Super Record 13, is its gravel-specific evolution: the “X” rear derailleur.\u003cbr\u003e\u003cbr\u003eBuilt on the same technical architecture as the Super Record 2x13 derailleur, it redefines shifting performance even on the roughest terrain. Thanks to an optimized derailleur path, it delivers smooth, fast, and immediate gear transitions—even under high pressure on the pedals —maximizing efficiency across the entire cassette range.\u003cbr\u003e\u003cbr\u003eThe key distinguishing feature compared to the road version is the new Nano Clutch, a miniaturized clutch that maintains optimal chain tension on uneven terrain and rough descents, preventing chain drops from the front chainring and ensuring maximum stability.\u003cbr\u003e\u003cbr\u003eCombined with the dedicated 1x chainring tooth profile, the Nano Clutch forms a system specifically engineered to minimize chain drops even in the most demanding conditions.\u003cbr\u003e\u003cbr\u003eThe new architecture, with the rear derailleur positioned beneath the cassette, delivers a cleaner aesthetic, improved aerodynamics, and perfect alignment between pulleys and gear ratios. The result is quieter, more precise, and more reliable shifting. Despite similar size and weight to the road version, Record X offers category-leading impact resistance and cage stiffness.\u003cbr\u003e\u003cbr\u003eEfficiency is further enhanced by two differentiated pulleys: the upper 12-tooth eccentric pulley maintains optimal chain distance even with large cassettes, while the oversized 16-tooth lower pulley improves chain engagement and smoothness. Both feature a profile designed to guide each link precisely, ensuring continuous and efficient chain flow.\u003cbr\u003e\u003cbr\u003eAnother key feature is the new cage geometry, with an extended body cage compatible with cassettes up to 48 teeth, ideal for tackling the steepest climbs. The crankset has also been optimized for gravel use, retaining Ultra-Torque technology with a 47.5 mm chainline — perfect for modern frames and increased tire clearance.\u003cbr\u003e\u003cbr\u003eThe derailleur features a universal mounting design, compatible with both UDH (Universal Derailleur Hanger) and traditional hangers. It is powered by a removable battery with a range of up to 750 km and ultra-fast charging: just 60 minutes are needed to reach full capacity. Battery status can be easily monitored via the integrated LED, the MyCampy app, or compatible cycle computers. The USB-C connector ensures full compatibility with modern devices, including smartphones that can be used as power banks in emergency situations.\u003cbr\u003e\u003cbr\u003eThe charging system and cable are shared across the entire 13 platform.\u003cbr\u003e\u003cbr\u003eThe design also reflects Campagnolo excellence: the front section of the cage is made of carbon with a direct-from-mold finish, while anodized aluminum components with tone on tone details  and the  refined branding highlight the brand’s attention to detail.\u003cbr\u003e\u003cbr\u003eThe result is smooth, fast, precise, and silent shifting even in the most extreme conditions. Additionally, thanks to compatibility with road 1x cranksets featuring a 45.8 mm chainline, the X derailleur enables single-chainring road setups with one of the widest gear ranges available on the market.\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePrecise, smooth, efficient, and reliable shifting performance in all riding conditions.\u003c\/li\u003e\n\u003cli\u003eThe redesigned derailleur positioning improves aerodynamics while ensuring optimal alignment with the cassette.\u003c\/li\u003e\n\u003cli\u003eEquipped with Nano Clutch technology, a miniaturized clutch system that guides the chain through every pedal stroke, maintaining ideal tension and preventing chain drops.\u003c\/li\u003e\n\u003cli\u003eThe pulley system is engineered to accommodate cassettes up to 48 teeth, delivering outstanding performance on steep climbs and rough terrain.\u003c\/li\u003e\n\u003cli\u003eCompatible with universal hanger standards, including UDH and traditional derailleur hangers.\u003c\/li\u003e\n\u003cli\u003eUnLock System: a manual release mechanism that allows the derailleur to be repositioned manually in case of system malfunction.\u003c\/li\u003e\n\u003cli\u003eRefined design down to the smallest detail, featuring carbon and aluminum components with branding integrated directly into the manufacturing process.\u003c\/li\u003e\n\u003cli\u003eRemovable battery, easily rechargeable via magnetic quick-snap ports, shared across the entire Platform 13 range.\u003c\/li\u003e\n\u003cli\u003eIntegrated position sensor: 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":50539832344674,"sku":null,"price":576.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/9695\/9330\/files\/Campagnolo-Record-X-Rear-Derailleur-01.jpg?v=1790218276","url":"https:\/\/www.twohubs.com\/products\/campagnolo-record-x-rear-derailleur","provider":"twohubs cycling boutique","version":"1.0","type":"link"}
