Chainring 110pcd Shimano Ultegra FC-R8100 12-speed

Elevate your cycling performance with the Shimano Ultegra FC-R8100 chainring, a precision-engineered component designed for the modern cyclist who demands both performance and reliability. This 12-speed chainring represents the cutting edge of drivetrain technology.

Bolt Circle Diameter (PCD): 110mm

The 110mm PCD (Pitch Circle Diameter) refers to the diameter of the circle formed by the centre points of the chainring's bolt holes.

This standardised measurement ensures compatibility with compatible crank-sets and allows for precise chainring replacement or upgrades.

12-Speed Compatibility

Engineered specifically for 12-speed drivetrains, this chainring features optimised tooth profiles and spacing designed to work seamlessly with modern 12-speed chains and cassettes for flawless shifting performance.

Ultegra-Grade Construction

As part of Shimano's Ultegra groupset family, this chainring delivers professional-level performance with materials and manufacturing precision typically found in racing applications.

Optimised Tooth Profile

Each tooth is carefully shaped to facilitate smooth chain engagement and release, ensuring crisp shifting under power while minimising chain drop and noise.

Lightweight Design

Advanced materials and strategic weight reduction techniques provide an optimal strength-to-weight ratio, helping reduce rotational mass for improved acceleration and climbing efficiency.

Durability Engineering

Built to withstand the rigours of intensive training and competition, featuring wear-resistant materials that maintain shifting precision over thousands of miles.

Understanding Chainrings

Chainrings are the toothed rings attached to your crankset that drive the chain.

The number of teeth determines your gear ratios - fewer teeth provide easier pedalling for climbs, while more teeth offer higher speeds on flats and descents.

The FC-R8100 series offers various tooth count options to match your riding style and terrain preferences.
