You, or more specifically, your choice of frame, motivated us to address challenges related to bottom bracket installation and durability – thank you. We embraced the task to improve upon so-called bottom bracket standards to give you the UBB4630. Crafted from 7000 series aluminum alloy, the UBB4630 uses a threaded sleeve to lock both cups in place – without having all the locking effort rely on the press fit shell, thus providing a uniform spin and avoiding undesired noises. The flush fitting in the press fit region prevents bearing overload and also improves bearing alignment for a longer bearing life. The external bearing location affords a smoother spin and increased BB shell stiffness for PF30 and BBright standards. The internal sleeve also prevents cable guides from rubbing against rotating parts. Features: Characteristics: 109 gr Compatibility: BB386

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.
