DUB 73mm Super Boost Bottom Bracket
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 for use with Super Boost cranksets due to the requirement of a 4.5mm spacer required on the outer left side (non-drive).
