Our T47 BBs are machined to precision with the highest quality aluminium and bearings. They will fit 30 mm spindle cranks with the included washers, or can be fitted with our adapter kits to accept other crankset spindle standards. The BB sleeve has been designed to leave room for internal cable routing. Servicing or replacing bearings is an easy job thanks to easily accessible bearing races, even when the unit is screwed into the frame. Outer seals provide extra protection for the already double-sealed bearings. Our PRO BBs use 2x 6806 bearings (30 x 42 x 7mm, ID x OD x W).

Seido offers adapter kits that enable the use of 29mm, 24mm and 24/ 22mm axle diameter configurations.

In the Summer of 2025, we took a deep dive into the subject of T47 bottom brackets, with our dedicated T47 blog post. Take a look at the blog section of our webstore to check out some of our other articles and interviews too.

Cheap Garbage
Color: Black, Size: 4 Panel
This item is just cheap crap. Shoddily put together, shoddy materials, and looks cheap. If you’re just putting it in a space that you don’t really care that it’s cheap, then it might be fine for what you need. But don’t expect much.

Keeps areas separated
Color: Black, Size: 6 Panel
Item arrived quickly. I use this to keep my cats out of a part of the cellar. Works great. They've figured out how to slip through side. I made a panel that covers those spots. Still the best item to keep area separate.

Nice panels

Gives good coverage, nice dark panels. Easy to assemble, light product and sturdy. I will recommend this item! Completely covers the back shelves that are for employees only.

Good Product
Size: 3 Panel-102'', Color: Beige
I got these dividers for outdoor use for some privacy from neighbors. They arrived quickly and were easy to set up. They look good, and though the legs don’t offer stability against any amount of wind—which I expected as it wasn’t advertised for outdoor use—all it took was placing a cinder block on the feet to hold it up right. Coverage is good, it’s easy to fold and move as needed, and it’s light weight. All in all a decent product. I will caution the purchase of “used like-new,” as both of the dividers I ordered were previously returned items, and one came missing a cap, instructions were not included, and the poles were all mixed up and not properly labeled. If I had not ordered a second divider (which did include the instructions) I would have had a much harder time figuring out which pieces were which and how to put them together.

So versatile! Perfect solution for dividing a room.
Size: 4 Panel-88'', Color: Grey, Size: 4 Panel-88'', Color: Grey
Perfect solution for my space. My office has to double as the hangout room for the kids and I wanted something that would block off my computer so it is left alone. This space allows me to close off my computer as much or as little as I want. It is lightweight yet has sturdy feet. This is important so that if it gets bumped it won’t topple over. The price was great and the build time wasn’t too bad! I would recommend two people for set up. I went with the grey panels and I think I’ll end up hanging some twinkle lights at some point. Great purchase!
