SRAM DUB bottom brackets are designed to connect crankarms and power to the drivetrain using a single, oversized DUB spindle that is compatible with all bottom bracket standards. They feature an improved Gutter Seal Technology for better protection against the elements, sealed cartridge bearings (available in steel or ceramic), and are engineered to be stronger, smoother, and more durable.
