What kind of bottom bracket is this?
(disclaimer about grammar errors, spanish is my native lang)
Hello I have a (I suppose is) a Chinese cheap clone of a Raleigh Roadster the brand is "Steed" never heard of or found nothing on Google, it has a bottom bracket at first i tough it was a simple cheap cup type square tapered, but i cant recognize the cups system it has. I have tools to install and disasemble sealed cartridge, and also have some experience removing the cup type squared tapered, but with this i have to destroy the crank (so cheap that it bents with two hammer punches) and the other crank arm , the two have a cover that goes over de cups, i include some pictures, i failed to capture more details....i dont know why i cant upload photos or put an URL but you can find the pics in www.iades.com/bb1.jpg , www.iades.com/bb2.jpg and www.iades.com/bb3.jpg

Regardless of account age, you need 10 posts in order to post links (to stop spambots.) As this is a legitimate request, here's a photo assist:

Taking some measures and doing some research maybe is a Thompson/Thun for square taper single crankset, i meassured and the outside diameter of the bike shell is 45mm, the inside diameter is 37 mm, and i measure the cups and the inside dimeter is 40mm and the outside 45 mm, in my country they sell a generic thompson bottom bracket at 2 dlls with 40mm inside diameter measure, i hope that this could help someone in my same situation

It looks like it might be something like this:

If the side of the bearings shown in your photo faced outward and the cup holding them was pressed into the frame, it’s a frame that can take a one piece crank, and so this is an unusual three piece crank that will fit that type of frame.
