The heart of this innovative solution is its carbon fibre structure, which guarantees absolute rigidity, super-light weight, and consistent power transmission. The result is continuous, smooth, and effective power that accompanies the rider through every pedal stroke.\u003c\/p\u003e\n\u003cp\u003eThis carbon structure is combined with teeth in 7075 aluminium alloy, an aeronautical-derived alloy chosen for its extraordinary light weight and endurance under the most demanding loads. Thanks to the high-thickness, hard oxide heat treatment, the ULTRA chainring maintains high performance over time, ensuring reliability and durability for both the chainring and the chain.\u003c\/p\u003e\n\u003cp\u003eEvery stage of production is precisely controlled: the composite is stabilised under exact temperatures and pressures to align carbon fibres perfectly. This showcases Campagnolo's mastery of advanced materials. Designed and built entirely in the Vicenza factory, ULTRA blends technology, style, and performance. Its moulded logo and details reflect the elegance and craftsmanship that define Campagnolo.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"panel text-left\"\u003e\n\u003ch3\u003eFeatures \u0026amp; Benefits\u003c\/h3\u003e\n\u003cp\u003eCarbon fibre chainring structure for absolute rigidity, super-light weight, and consistent power transmission\u003c\/p\u003e\n\u003cp\u003eTeeth made of 7075 aeronautical-grade aluminium alloy, lightweight and engineered to withstand the toughest loads, treated with high-thickness hard oxide for greater durability\u003c\/p\u003e\n\u003cp\u003eProduction process that involves stabilising the composite at controlled temperatures and pressures to ensure perfect fibre orientation\u003c\/p\u003e\n\u003cp\u003eLogo and chainring details obtained directly from the mould, a testament to Campagnolo's expertise in working with the most advanced materials\u003c\/p\u003e\n\u003cp\u003eEngineering and design that collaborate to produce the most unique products\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"panel text-left\"\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eShifting experience: Wireless 13x\u003c\/p\u003e\n\u003cp\u003eDiscipline: Road\u003c\/p\u003e\n\u003cp\u003eE-Bike compatible: Yes\u003c\/p\u003e\n\u003cp\u003eIP69K: Maximum water pressure resistance class\u003c\/p\u003e\n\u003cp\u003eMaterials: Carbon fibre and 7075 aeronautical-grade aluminium\u003c\/p\u003e\n\u003cp\u003eQ - Factor: 148.5mm\u003c\/p\u003e\n\u003cp\u003eCrankset gearing: 34x50, 36x52\u003c\/p\u003e\n\u003cp\u003eASTM Category: 1\u003c\/p\u003e\n\u003cp\u003eWeight 34x50: 78g\u003c\/p\u003e\n\u003cp\u003eWeight 36x52: 102g\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Campagnolo","offers":[{"title":"CR02-UL1350 50T","offer_id":49150198808793,"sku":"CR02-UL1350","price":289.99,"currency_code":"GBP","in_stock":true},{"title":"CR02-UL1352 52T","offer_id":49150198841561,"sku":"CR02-UL1352","price":289.99,"currency_code":"GBP","in_stock":true},{"title":"CR02-UL135034 50T+34T Set","offer_id":49150198874329,"sku":"CR02-UL135034","price":399.99,"currency_code":"GBP","in_stock":true},{"title":"CR02-UL135236 52T+36T Set","offer_id":49150198907097,"sku":"CR02-UL135236","price":399.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0776\/7624\/9305\/files\/cpra760a.jpg?v=1787655087","url":"https:\/\/sprockets.uk.com\/products\/campagnolo-cr02-ul135-super-record-ultra-13-speed-carbon-chainring","provider":"SprocketsUK","version":"1.0","type":"link"}
