Contact us if you are unsure, and we'll help out.

Shimano's early alloy 10s freehubs (Shimano Dura Ace 7800 series hubs) had taller splines and only certain 10s cassettes will fit them (they have corresponding deeper slots).

Another way to say this is these certain 10s cassettes spline pattern and width (but not depth) is otherwise identical to all the other Shimano 10s cassettes.

Why taller splines for 10s? Initially 10s was only Dura-Ace. Shimano had seen that use by a strong rider could make the narrow steel sprocket dig into the softer metal of alloy freehubs (at that time only available on aftermarket hubs). When Shimano gave the new 10s Dura-Ace freehub an alloy body, they made the splines taller to resist this marring of the freehub.
