Sram DUB Threaded MTB Bottom Bracket
The SRAM DUB bottom bracket connects and protects the crankarms for a smooth, long-lasting application of power to the drivetrain.
SRAM engineered this oversized DUB spindle to work across every type of bottom bracket standard, simplifying crankarm compatibility.
It has sealed cartridge bearings and one oversized spindle to work across every bottom bracket standard.
It is significantly lighter than the GXP system.
With Gutter Seal Technology it drastically improves sealing and protection against the elements
