Bottom Bracket Help
 

For all the experts out there. I am in need of some sealed bearing BB cups. I have a nice early style Shimano UN54 BB that needs both cups. This is the version that didn't have the fixed cup attached. I can also use some Edco and Tange cups for both sides. There's not much if anything on ebay. Seems like you need to buy an entire BB just to get cups.

The current production the cartridge casing is all one piece, threaded in from the drive side.

and the sleeve threads in from the NDS , it is, just stabilizing , so can be plastic..

Which is why Shimano isn't selling the fixed cup anymore. But I still have a BB less cups on both sides. I hate to scrap it if that's all I need.

I have a set of Italian thread Edco cups and lockrings to sell , [in a bin somewhere]

Thanks but I need English. I'll have to make a trip to the LBS and see if they can come up with anything.

The first UN7X bottom brackets had the drive side cup as a firm slip fit over the cartridge bun not integral with it. If you can find one of those in the LBS's scrap bins that would be a source for what you need.

Great, thanks for the help. Now I know what to look for. This is why I love this place.
