These custom, Swiss made bearings are double sealed, fully serviceable and removable which give much greater life span than stock units. The bearings are made (as all Hope bearings are) by INA and have been designed to run directly on the crankset axle, without the use of shims or spacers -again increasing life and reliability. Hope use a non contact, free running labyrinth seal to protect the bearing externally, and the machined aluminium centre tube is sealed internally with o-rings. The unit is suitable for 73mm and 83mm shell width's.
This latest evolution of the BB introduced by FSA belongs to the press fit family. It has a symmetrical BB shell but with the same overall width of a BSA BB including the cups.
This road bike bottom bracket is suitable for use with both carbon and alloy BB30 cranksets. Designed for versatility, it comes equipped with stainless steel cartridge bearings that are pre-installed in nylon cups for smooth rotative performance on every mile. Compatible with BB386 EVO, 46mm pressfit (PF30), and BBRight frame standards, this FSA PF30 road bottom bracket is a great choice for reliable and consistent crank operation. One final highlight is it's developed with clearance to allow for the internal routing of wiring for Di2 or other electronic shifting systems. For SL-K Light, Energy, Gossamer Pro, Gossamer, Assault, Vision TriMax and Omega BB30 chainsets. Manufacturer's Part Number: 200-3112 Black PF30

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.

Ceramic bearings for improved performance and longevity.
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.
