Iso square CrMo axle with alloy forged cups and carbon body and sealed bearings Patented CNC ISO Square BB/Campagnolo Compatible.
The bottom bracket is a key component of every chainset. Smoothness movement is critical, yet must be balanced by enough sealing technology to sustain a reasonable lifetime of use. FSA MegaExo bottom brackets are the result of years of development and feature exclusive innovations to guarantee the best balance of efficiency and durability. FSA uses the state-of-the-art materials like Silicon Nitride formed ceramic ball bearings, or highly polished chrome steel ball bearings, depending on the level of the bottom bracket.

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.
