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.
This bottom bracket is compatible with PF92 bottom bracket Super Boost frames when using SRAM DUB style (28.99mm) crank spindle cranks
