Sram Dub Press Fit Bb386 Bottom Bracket Cups

The new SRAM DUB™ bottom bracket series has a simple job-connect your crankarms and protect the smooth, long-lasting application of power to your drivetrain. To allow that singular focus, we´ve engineered the DUB™ spindle to be the one true unifying component. One oversized spindle to work across every bottom bracket standard. For better crankarm compatibility. For better protection from the elements. For longer-lasting performance. To be stronger, smoother, simpler. Now, back to the ride.Features:- One oversized spindle to work across every bottom bracket standard- Greater bearing durabilitySpecifications:- Bb-Frame Interface: Bb30- Crank-Bb Interface, Dub- Bearing Type: Standard- Spindle Diameter: DUBTechnology:DUB™:- The relationship between bottom bracket spindle and bearing is the core of DUB™ technology. It's where stiffness meets durability. We took it a step beyond conventional thinking and made everything simpler—better integrating the relationship between chainring, crank, spindle and bottom bracket. It's this approach to developing a complete system that equals better drivetrain performance.
