Rotor UBB4630 386 BB Steel. 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.

It’s ok.
Color: Beige, Size: Upgraded Base-4 Panel
It works, but not a great product. The cloth is super thin, so do not expect to use it to block noise. Wants to bent and tilt with little effort to make it so. Will not stand straight. It is a good color though.

Too Short & Skewed Foot. Easy Build & Good Material.
Color: Black, Size: Upgraded Base-1 Panel, Color: Black, Size: Upgraded Base-1 Panel
The 3 partitions I purchased were of good material but were shorter than described and the "feet" on one end of all 3 partitions was skewed a few degrees so I cannot butt them together side by side. PHOTO #1: you see me who is 63.5 inches in my shoes standing next to the 72 inch described partition minus the wheels so it is fair to say it should be 70 inches. But even so, 70 inches minus 63.5 equals 6.5 inches that should be above my head and should not include the tip of the pole and a 6 inch gap below. PHOTO #2: shows the gap when a 90 degree good end is butted against the skewed end. Good material and easy construction but just make it taller and fix the jig that skews the bottom bracket weld.

Great for “pop up home office”
Color: Grey, Size: Upgraded Base-4 Panel
If you need a space for a video conference in a hurry or to make a private corner for a kiddo to nap in this is a perfect divider that blocks light and separates spaces. It was easy to put together and collapses down to a flat panel for easy storage out of the way.
