Description

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 the PF30 standard. The internal sleeve also prevents cable guides from rubbing against rotating parts.
