R4 520-120L SRS Road Chain

Description

The Renthal R4 520-120L SRS Road Chain is a high-performance sealed ring chain designed specifically for road applications. Utilizing Renthal’s innovative Self Regulating Seal (SRS) technology, this chain offers superior durability and smoother operation compared to conventional O-ring and X-ring chains. The SRS rings are pre-loaded during assembly, maintaining a tight seal to retain grease around the critical pin and bushing areas, while effectively keeping out dirt, water, and other contaminants. This ensures extended service life and reliable performance over time. Key features include high-strength alloy steel construction for the plates and pins, solid bushings and rollers, and shot-peened side plates for enhanced durability. The chain also boasts thicker inner and outer plates to increase fatigue resistance and larger diameter pins to withstand shock loads and reduce wear. Quad riveting on each pin further boosts tensile strength, offering an impressive average of 8,093 lbs. Additionally, the gold-anodized side plates provide corrosion resistance and a sleek finish. Pre-stretched for minimal adjustment during break-in, the chain comes with a rivet-style master link and a pair of latex gloves for clean and straightforward installation. The Renthal R4 SRS chain delivers exceptional performance, longevity, and smooth operation, making it an ideal choice for road riders seeking a reliable and durable upgrade.
