The SRAM DUB bottom bracket series has a simple job- to connect crankarms and protect the smooth, long-lasting application of power to the drivetrain. SRAM engineered the oversized DUB spindle to work across every bottom bracket standard, simplifying crankarm compatibility.
– Gutter Seal Technology™ drastically improves sealing against the elements – Sealed cartridge bearings – One oversized spindle to work across every bottom bracket standard – Significantly lighter than GXP system
