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) :daumenhoch:
-
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 :daumenhoch:
-
open cage bearings all use the same sized US bb cups so are fully interchangeable :daumenhoch:

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 :daumenhoch:

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... ;D

Ok great so the general consensus is that most bb cups will work with most open bearing set ups.
That's cool thanks gents ! :daumenhoch:

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 :2funny: :2funny:
Yes, they are all the same size internally where the bearings sit :daumenhoch:
If I can't find any, your local bike shop will have some for next to nowt ::)

If your axle is threaded (Not where the nuts/or bolts that hold the arms on) then chances are that any looseball US BB for a 1 pc crank will fit.If it`s not threaded then the kit below will fit.

Hi,
Theres nothing wrong with the parts I just need some new BB cups which Spen or (Seen) is sorting for me .
Good shout on the kit though I also have one of these kits on another build i'm just about about to complete (as soon as my pad set & seat arrive), i've hooked that bb kit up to a set of sugino gt cranks & (all good) ! :daumenhoch:
