Aluminum Ceramic DUB Bottom Bracket - 68/73mm

5Dev Aluminum Ceramic DUB Bottom Bracket is a premium threaded BSA bottom bracket built for riders running modern 29mm spindles, including SRAM DUB and 5Dev 29mm crank spindles. CNC-machined aluminum cups paired with Enduro XD-15 ceramic-hybrid bearings target low friction under load and long-term durability in real-world mud, washings, and big-mile training blocks.

Performance and install details that matter

1. 29mm spindle compatibility - Direct fit for SRAM DUB and 5Dev 29mm spindles for a clean, modern crank interface
2. Enduro XD-15 ceramic-hybrid bearings (ABEC-5) - Prioritizes smooth rotation and wear resistance where bottom brackets typically fail first
3. CNC-machined aluminum cups - Precise cup/bearing alignment for consistent bearing life and quieter operation
4. Standard DUB BSA tool interface - Installs with a standard SRAM DUB BSA bottom bracket tool for straightforward service
5. Limited lifetime bearing warranty - Adds long-term value for riders who put serious hours into a single bike
