{"title":"derailleurs - rear","description":"","products":[{"product_id":"campagnolo-super-record-13-rear-derailleur","title":"Campagnolo Super Record 13 Rear Derailleur","description":"The strength of the new Super Record 13 lies in the chain motion path along the gear scale: it has been optimized in order to obtain the most immediate, smoothest and fastest gear change possible. Which means that, in completing the entire scale, the new Super Record 13 is faster than any 12-speed gearbox, which has one sprocket less, on the market today. \u003cbr\u003e\n\u003cbr\u003e\nThe two pulleys of the derailleur cage have been increased to 14 teeth with a differentiated profile: the larger diameter reduces friction between the chain links as they pass through the derailleur cage and on the bearings which, in the upper guiding pulley, are made of ceramic to eliminate any drag and enhance the precision of the chain motion. The lower tensioning pulley is designed for efficient performance over time as the kilometers go by. Two frame engagement options: one with the new original Campagnolo UDH dropout by direct assembly and the other one via a fixing link for traditional dropouts.\u003cbr\u003e\n\u003cbr\u003e\nCampagnolo presents a new Super Record 13 groupset, the fastest on the market, capable of offering a greater choice of gear ratios that allows you to find the best pedaling cadence. \u003cbr\u003e\n\u003cbr\u003e\nA new chapter in the history of Campagnolo begins but one that has deep roots, and more precisely dates back to 1973, the year in which the Super Record was born and would from then on write some of the most iconic pages of the history of modern cycling. With over 50 years of history, the product born in the factories of Vicenza became synonymous with technical excellence and Italian style.\u003cbr\u003e\n\u003cbr\u003e\nAnd Campagnolo continued to offer that extraordinary product range in the years that followed, standing as a point of reference for the entire industry and being the first company in the world to use a 10-speed, then an 11-speed and later a 12-speed groupset in road cycling.\u003cbr\u003e\n\u003cbr\u003e\nToday, in the wake of this tradition of absolute innovation, Campagnolo launches a world premiere: the new Super Record 13, the first road groupset equipped with a 2x13 derailleur. A completely redesigned solution dedicated to those seeking maximum performance, innovation and style.","brand":"Campagnolo","offers":[{"title":"Default Title","offer_id":42971189837922,"sku":null,"price":938.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/9695\/9330\/files\/Campagnolo-Super-Record-13-Rear-Derailleur-01.jpg?v=1780007098"},{"product_id":"shimano-dura-ace-rd-r9250-rear-derailleur","title":"Shimano Dura Ace RD-R9250 rear derailleur","description":"The fastest ever shifting across SHIMANO's widest ever DURA-ACE gear range, the RD-R9250 is capable of both race wins and personal bests.\u003cbr\u003e\n\u003cbr\u003e\nThe DURA-ACE RD-R9250 integrates the system charging port and a wireless connectivity unit all while delivering super fast, precise shifting worth of any podium.
