This \r\nmakes it an ideal upgrade for riders seeking improved performance \r\nwithout compromising durability.\u003c\/p\u003e\u003cp\u003eUsing FEA-based stress contour \r\nanalysis, Magene reinforces high-load areas to minimise flex under \r\npower, ensuring consistent performance during sprints, climbs, and \r\nlong-distance efforts. Precision CNC machining guarantees uniformity, \r\naccurate tooth shaping, and perfect alignment for reliable drivetrain \r\nengagement.\u003c\/p\u003e\u003cp\u003eMagene's third-generation tooth profile enhances chain\r\n retention, shifting speed, and overall transmission efficiency. \r\nRedesigned tooth roots, grooves, and shapes allow the chain to move from\r\n the small ring to the big ring in as little as one-fifth of a crank \r\nrevolution, even under heavy load.\u003c\/p\u003e\u003cp\u003eCompatible with 110 BCD 4-bolt \r\nsystems, the QED chainring integrates seamlessly with Magene's P505 \r\npower meter and supports 11 and 12-speed Shimano groupsets (excluding \r\nShimano cranksets with unique shapes).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eWeight: 143g (50-34T)\u003c\/li\u003e\n\u003cli\u003eCompatibility: Shimano 11 and 12 speed\u003c\/li\u003e\n\u003cli\u003eBolt: 4 Bolt\u003c\/li\u003e\n\u003cli\u003eChain Line: 45mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e7075 aircraft-grade aluminium\u003c\/strong\u003e for ultra-light weight and high stiffness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOnly 143g\u003c\/strong\u003e total weight with exceptional durability\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFEA-optimised\u003c\/strong\u003e structural reinforcement to reduce deformation under load\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCNC precision machining\u003c\/strong\u003e for consistent quality and accurate tooth geometry\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e110 BCD 4-bolt compatibility\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eFully compatible with Magene P505 and PES P505 power meter systems\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupports Shimano 11 and 12-speed groupsets\u003c\/strong\u003e (except Shimano-shaped cranks)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurability tested with over 100,000\u003c\/strong\u003e fatigue cycles and 40,000 km endurance testing\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Magene","offers":[{"title":"QED Split Chainring 50-34","offer_id":57098103259468,"sku":"MA50100A","price":75.0,"currency_code":"GBP","in_stock":true},{"title":"QED Split Chainring 52-36","offer_id":57098103292236,"sku":"MA50100B","price":75.0,"currency_code":"GBP","in_stock":true},{"title":"QED Split Chainring 53-39","offer_id":57098103325004,"sku":"MA50100C","price":75.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1041\/5715\/1564\/files\/ma50100a.jpg?v=1774604856","url":"https:\/\/eatcycling.co.uk\/products\/qed-split-chainrings","provider":"EAT Cycling","version":"1.0","type":"link"}
