Key benefits - Safe, efficient design: high precision machining and an integrated construction provide reliable performance over time. Enhanced support features and optimized tooth profile help keep the chain engaged for consistent power transfer. - Narrow-wide aluminum chainring: aluminum alloy construction with a positive and negative tooth profile to reduce chain drop and handle strong power delivery. - Quiet, smooth operation: tooth thickness is machined to work seamlessly with inner and outer chain links, lowering friction and minimizing noise. - Broad compatibility and sizing: 110/130 BCD with a wide range of tooth options to fit your setup. Specifications - Size: 110/130 BCD - Splines: 36T, 38T, 40T, 42T, 44T, 46T, 48T, 50T, 52T, 54T, 56T, 58T, 60T - Material: aluminum alloy - Tooth profile: includes positive and negative elements to prevent chain drop - Designed to match inner and outer chain links for reduced friction and quiet operation Use scenarios - Time trial or performance road riding: optimized for steady cadence and reliable chain retention during high-power efforts. - Road, gravel, or cross-country upgrading: improves chain retention and reduces drivetrain noise on varied terrain. - Chainring replacement or upgrade: compatible with standard 110/130 BCD cranks, available in multiple sizes (36T–60T) to tailor gearing to rider preference and terrain.
