Axe30 BSA Thread BB, 30mm, 68/73mm

DMR Axe30 BSA Thread Bottom Bracket is a purpose-built, BSA-threaded (English) bottom bracket designed specifically for the DMR Axe crank’s unique 30mm axle. Built with sealed cartridge bearings in cups made by Praxis for long service life, it’s a clean solution for riders who want the simplicity and durability of a threaded bottom bracket in a 68/73mm frame shell.

• BSA threaded fit (68/73mm) - Threaded installation helps reduce creaks and simplifies service compared to many press-fit systems
• 30mm-specific for DMR Axe - Correctly matches the DMR Axe crank spindle for proper bearing support and alignment
• Sealed cartridge bearings - Helps keep water and grit out for consistent rotation and longer bearing life in wet, dusty, or high-mileage use
• Praxis-made BB cups for DMR - Proven manufacturing and sealing approach aimed at real-world durability
• Requires M30 BB tool - Uses the specific M30 bottom bracket tool for correct installation and removal
• Compatibility note - Not cross-compatible with other 30mm crank systems or other 30mm bottom brackets; DMR Axe cranks require this Praxis-built Axe bottom bracket
