Key benefits - Reduces friction and noise by using a tooth geometry that engages the chain smoothly with both inner and outer chain links. - Narrow-wide chainring design improves chain retention on standard drive trains, helping prevent drops during riding. - Aluminum alloy construction provides a strong, lightweight solution for demanding cycling conditions. Fit and compatibility - Fits most 110/130 BCD cranks. Before purchase, please confirm your crank BCD and the number of teeth to ensure proper compatibility. Materials and construction - Aluminum alloy chainring engineered for durability and light weight. - Tooth geometry features positive and negative elements to support secure chain engagement and reliable performance. - Integrated machining delivers precise tolerances for consistent function and efficiency. Design and performance - Safe and efficient design suitable for time trial and fast riding environments. - Advanced plus or minus tooth profiles enhance chain support and engagement, helping the chain operate more effectively under load. Usage scenarios - Road cycling upgrades: replace an worn or noisy chainring on a 110/130 BCD crank to improve smoothness and reduce drivetrain noise. - Time trial or single-ring setups: use as a lightweight, reliable chainring when configuring a dedicated race or training bike with a single front ring. - General maintenance and replacement: a solid aluminum option to restore performance on compatible cranks without adding unnecessary weight. Notes - Verify your crank’s BCD and the number of teeth prior to purchase to ensure proper fit and performance.
