The Shimano Tiagra CS-RS400 11-speed cassette is engineered to provide road cyclists with smooth, reliable, and precise shifting performance. Specifically designed for the Tiagra R4000 11-speed groupset, this cassette incorporates advanced Hyperglide sprockets featuring a computer-optimised tooth profile and contoured shift gates. These innovations ensure crisp gear changes even under heavy pedalling loads, enhancing your riding experience on varied terrain.
With a low 36-tooth sprocket, the cassette facilitates easier climbing on steep gradients, making it a practical choice for riders who demand versatility and efficiency. The cutaway sprockets reduce overall weight without compromising structural integrity, contributing to a responsive and agile drivetrain. Finished with a nickel-plated coating, the cassette resists corrosion and maintains its professional appearance over time, while the corrosion-resistant steel lockring further enhances durability and longevity.
As a key component within the road bike transmission system, the Shimano Tiagra CS-RS400 cassette is an essential upgrade for cyclists seeking dependable gear transitions and consistent performance in training or competition environments.
Is this cassette compatible with other Shimano groupsets?
This cassette is optimised specifically for the Tiagra R4000 11-speed groupset and may not provide ideal shifting performance with other Shimano groupsets.
Can I use this cassette with any 11-speed chain?
Yes, it is compatible with all standard 11-speed chains designed for road cycling, ensuring smooth operation across the drivetrain.
What accessories complement this cassette?
To maximise performance, consider pairing the cassette with compatible pedals, helmets, and lighting systems for enhanced safety and efficiency during rides.
