DC-R40 is specified as an MTB rear hub with a disc ISO 6 holes design and a Shimano HG 8-12 speed alloy HG cassette. This combination defines the disc rotor mounting interface (ISO 6 holes) and the drivetrain interface (Shimano HG 8-12 speed) as provided in the product information. For product managers and wheel builders, keeping these exact terms consistent across product pages, specification sheets, and purchase orders helps avoid confusion and ensures the correct hub standard is selected.
The installation guidance provided for DC-R40 describes it as a boost rear wheel hub and states that you will need a through axle with OD 12mm to lock into the frame. The OLD is provided as 148mm for hub total length. Therefore, this page lists 148mm OLD and through axle OD 12mm as the key assembly requirements to be checked against the bike frame specification. No additional claims about compatibility with other standards are added, because the objective is to keep technical information strictly aligned with what is supplied.
For the hub drive mechanism, the provided text specifies that the rear hub drive system is using 6 pawls and springs with a 54 tooth ratchet ring, which allows 108t engagements. These values and phrases are included in both the specification table and the description to support SEO for technical search queries while preserving the exact wording and numbers from the provided data.
In website implementation, DC-R40 can be supported by structured content elements such as a technical specification table, feature bullets, FAQ blocks, and internal links.
