Campagnolo CR02-UL135 Super Record Ultra 13 Speed Carbon Chainring

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

Campagnolo's constant pursuit of excellence has led to the creation of ULTRA, the carbon chainring designed to transform every pedal stroke into pure performance. 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.

This 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.

Every 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.
