What will replace the quality of the discontinued Shimano BB-UN55?

[GuyBoden]

With the Shimano UN55 BB out of production/discontinued, I'm just wondering what BB will replace the quality and reliability of the ubiquitous Shimano UN55 BB, preferably at the same price range.

Obviously, Chris King and Phil Woods BBs are available for folk with plenty of cash.

I'm just thinking about what my next square taper BB choice might be.

We've a couple of Velo Orange square taper BB's. They're pretty and pricey but very high quality.

King won my heart at Bespoked, so Phil Wood will always come 2nd in that race.

You can bet there will be makers willing to plug the gap for this popular item. There's loads on eBay, never heard of Neco before, £14.

With ST BBs going on for intergalactic mileages I should think it's going to be while before you need another

I've just fitted a shimano UN300. I assumed that was the spiritual successor to the UN55?

That's what I thought...

Spa Cyckes will no doubt come up with or source similar.

Looks like it.

Not too dear at about twenty quid given the context of increasing prices for bike bits.

Yes, I know, but, are they as durable as the UN55, only time will tell.

Spa Cycles seem to be using First Components DX-30 or F2001 BBs on some of their own bikes, they're BBs made in Taiwan.

I've used Halfords own brand VP bottom brackets, cheap as chips (tenner), and steel collars both sides - no issues.

IRD Quad look good too, made in Japan by Tange, that's if you can get them in the UK, Sjscycles might get them in stock.

Still run replacable BB's on all my square taper bikes, as long as you keep on top of maintainance* they last almost indefinitly

* plenty of grease

very probably, Shimano are unlikely to have forgotten how to make decent BB's just because they've changed the part number a bit.

they look and feel pretty similar
