I'm happy with the crank on my single speed and just need to replace the square taper bottom bracket. I'm used to just seeing the complete (non-servicable) ones from Shimano. Just browsing ebay, I see quite a few bare titanium spindles, e.g.

How would I fit one of these, i.e. which bearings and end caps would fit a typical 68mm threaded bottom bracket? This type of bb is completely new to me..

Possibly they will fit inside a dismantled UN-91 Shimano BB or a set of Real cups and bearings.

Without dimensions it's hard to tell indeed!

Thanks for the tips - I googled the UN-91, all I found was that the bearing is "permanently" press-fit onto a the spindle...

What are "Real" cups/bearings?

I'll ask the seller for more info - the diameter should tell us a lot eh?
