The threaded UBB4630 is designed to solve issues with PF30, BB386 and BBright Bottom Brackets.
Rather than relying on the pressfit shell for alignment, the UBB4630's threaded sleeve locks both cups in place, increasing BB shell stiffness. This also ensures a smooth, uniform spin free from creaks that often plague pressfit while preventing bearing overload. The perfect alignment also means longer bearing life while the sleeve also prevents cable guides rubbing against rotating parts. "The motive for the UBB4630 was to address challenges related to bottom bracket installation and durability with specific frames," said David Martinez, head of engineering at Rotor.
