The new Campagnolo ULTRA chainring in carbon fiber has been designed to guarantee super-light weight, rigidity, and performance over time.

• Carbon fiber chainring structure for absolute rigidity, super-light weight, and consistent power transmission.
• Teeth made of 7075 aeronautical-grade aluminum alloy, lightweight and engineered to withstand the toughest loads, treated with high-thickness hard oxide for greater durability.
• Production process that involves stabilizing the composite at controlled temperatures and pressures to ensure perfect fiber orientation. 
• Logo and chainring details obtained directly from the mold, a testament to Campagnolo's expertise in working with the most advanced materials.Engineering and design that collaborate to produce the most unique products.
• 50 T – only 78g (34g less than the 50-tooth Super Record chainring) to be combined with a 34-tooth internal chainring.
• 52 T – only 102g (28g less than the 52-tooth Super Record chainring) to be combined with a 36-tooth internal chainring.
