Box Four Cassette

This cassette is designed for standard HG freehub bodies, which are the most common mountain bike hubs. If your current wheel uses a standard Shimano/SRAM HG-style freehub, this will install without any adapters.

No, this cassette is specifically engineered for 8-speed drivetrain systems. You will need an 8-speed shifter and derailleur to ensure the gear indexing and spacing align correctly.

The ED (Electrophoretic Deposition) black coating is primarily for durability. It provides a robust barrier against corrosion and wear, helping the steel teeth maintain their shape and finish even after exposure to mud, water, and grit.

Yes, with an 11-42 tooth range, this cassette provides a generous spread for climbing. It is designed to give you a low enough gear for steep ascents while maintaining a high enough gear for pedaling on flatter sections.

The wide/narrow tooth profile is specifically optimized for 8-speed chain geometry. This design helps improve chain retention and ensures smoother, more reliable gear transitions under load compared to generic tooth profiles.
