1 pc & 3 pc BB fitting kits. (stupid question probably)

[Funkyworm]

Ok so I need some new shiny bb cups to go on my new build,

I have my crank (Sugino ct 175) & it came with the spindle bearings etc , in fact everything including the fitting bolts etc but no BB cups.

I'm assuming that all USA BB cups are the same whether a 3piece or 1piece crank is to be used ?

When you see a full kit being advertised I'm assuming it's the fitting hardware thats differentiates a 1pc to a 3piece kit as 3 piece cranks use a spindle which is narrower than the internal part of a 1 piece crank arm hence the fitting bolts etc have a smaller diameter .....


Basically can i use any BB cup

Cheers

okay, i think (and someone will correct me if i'm wrong) that all loose ball BB's use the same cups.

Sealed bearing US BB's use a completely diferent sort of cup as the face that the bearing sits on is machined flat rather than a rounded cup for loose ball cages.

hope that makes sense (and is correct)

I've heard the argument that Tange BB's use "proper" Tange cups but personally I think that was tosh as i've swapped so many around over the years but left the cups in situ and i've never had a problem - thats talking loose ball.

Sealed is a different matter and the internal cup profile can vary depending on the manufacturer - I always remove the cups that came with a sealed BB and keep the sets together.

agree, with sealed bearings that have cups rather than new school where most of them press into the frame, i would keep the cups with the bearings

open cage bearings all use the same sized US bb cups so are fully interchangeable

Did you punch the screen...?!

Yep, agree with that. I have swapped, bought or traded framesets that still had the cups left in, I left in, and I used them, they used them. They all fit all looseball cages

There you go - four of us telling you you're good to go and then there's Rich... I'm surprised he didn't contribute with a comment about jelly beans, tree rings or argyle socks...

Ok great so the general consensus is that most bb cups will work with most open bearing set ups.

That's cool thanks gents !

Ha-ha where's the (like) button when you need one 

Anyone got any new bb cups to sell?

Fookin hell Callum...... just send me a list of everything you need to finish your builds off.

I'll delay posting that shite to you and have a look tonight for a set to chuck in the envelope FoC if I have some...... despite the fact that you will probably haggle on the free price

Yes, they are all the same size internally where the bearings sit

If I can't find any, your local bike shop will have some for next to nowt

Seen means Spen. Poor lad. He has trouble with shoe laces as well I hear......

So I've heard, it' dangerous in the hands of the un educated.
