HSC BB30 Ceramic Adapter Bottom Bracket

HSC's BB30 adapter bottom brackets enable the use of various cranksets in BB30 frames. Crafted from aluminum, they fit Shimano HollowTech II, SRAM GXP, DUB, and BB386 EVO cranks. The design enhances drivetrain stiffness and power transfer.

Incorporating hybrid ceramic bearings with silicon nitride balls, they offer reduced friction and increased durability with alloy steel races and dual-lip seals. Suitable for 68mm BB30 shells, these adapters are durable and efficient.
