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.
Rotor UBB4630 Steel Bottom Bracket"The motive for the UBB 4630 was to address challenges related to bottom bracket installation and durability with specific frames," said David Martinez, head of engineering at Rotor.The UBB 4630 Bottom Bracket uses a threaded sleeve that locks both cups in place, increasing the stiffness of the bottom bracket shell. It also eliminates one the most common and frustrating issues with pressfit bottom brackets, creaking, while ensuring free and smooth spinning cranks. As perfect alignment is achieved, you can expect longer bearing life and the sleeve prevents cables and guides rubbing against moving parts.Features: Material: 7000 series Aluminium Threaded installation Weight: 109gBuy Rotor Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

Ceramic bearings for improved performance and longevity.
Rotor BB1 BSA Ceramic Road Bottom BracketRotor set out with the goal of creating a bottom bracket unlike anything currently available on the market with a flashy and aesthetically appealing look.The BB1 is incredibly light and is sure not to go unnoticed, and the smooth unobtrusive lines marry perfectly with any type compatible crankset, be it made of carbon or aluminium. The BB1 is available in black colour with steel bearings, Enduro Grade5 Ceramic and Enduro Grade3 Ceramic. The steel option offers a light and elegant bottom bracket at a very competitive price while the ceramic bearing options are ideal for those looking to shed every possible gram while at the same time acquiring an incredibly smooth bottom bracket. Both versions are available for road (BSA only) as well as MTB use. The ceramic versions come in at an incredible 91g for the road model, and 95g for the MTB, while the steels comes in at 97g for road and 101g for MTB; still quite impressive.Features: BB1 BSA FOR BSA FRAMESteel: 96g, Ceramic 91g.Black anodized and lasered design.Lathe and CNC T6 heat treated 7075 Aluminium.Labyrinth seals prevent bearing contamination.For all ROTOR and Shimano compatible 24mm cranks.Buy Rotor Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
Hope's tested and proven stainless bottom brackets are now available in a road specific version and make an ideal upgrade or replacement for Shimano, Race Face and with an additional conversion kit (sold separately) Truvativ/SRAM road cranksets.The machined aluminium cups hold full stainless steel INA Swiss made cartridge bearings which are custom made to give much greater life span than stock units and are also replaceable to reduce wastage and minimise expense. The bearings are designed to run directly on the crankset axle, without the use of shims or spacers for increased lifespan and reliability when combined with the non contact, free running external labyrinth seal and o-rings on the lightweight internal aluminium centre tube.
