Bottom Bracket Advice

[RyanW]

Hi All,

I need to replace a Shimano BB UN52 68 with a campagnolo compatable one.

Any suggestions. Im looking second hand but dont know what im really looking for. I do not know what cranks im going with, i guess it depends on the BB?

You need to get the cranks first - they will need a certain sized axle (this can vary between cranks).

I might have something in the shed (Mirage square taper) - I'll pm you tomorrow.

I take it that you are aware the the taper on Campag BBs is different from that of Shimano?

 

[RyanW]

Yeah, i need a new crankset / bb set up to work with campy shifters and derailleurs with a 9 speed campy rear casette, i do not mind what it is, i just need it to fit where the above bottom bracket was removed from. My only previous bb experience was a 1960s raleigh, and as you know this is worlds apart.

 

[RyanW]

for example, will this work:

FSA Omega Crankset Compact with Bottom Bracket​

Rings : 50/34T
Crank arm length : 170mm
Including Bottom bracket BB-AL86 dia 19 B3044.

I'd have a look at this item


http://www.ebay.co.uk/itm/Campagnol...ikeparts_SR&hash=item1c289054e8#ht_500wt_1202

Compact and has external bearings - so you don't need a BB - just the cups (£18).

 

[RyanW]

are all bb cups one size?

 

[RyanW]

and can you use any, or is it a specific cup for a specific set?

 

[accountantpete]

Basically Campagnolo has the bearings attached to the cranks so you just need the cups. They are either Italian or English thread.

Shimano/SRAM have the bearings attached to the cups and you just thread the axle through - again Eng or It.

You would really need to see a pair to appreciate what is going on.

 

[RyanW]

See a pair! sounds like a joke

I have been trying to research it but info is thin on the ground. It seems you either buy the set or need to know whats happening. I have seen some FSA sets which seem to ne campag style in BB on the cranks. I just need to get hold of anything at the moment.

If you're set on buying an FSA (ie 3rd party) crank - why does it need to be Campag compatible..??

Dawes Ultra Galaxy Bottom Bracket Sugino failed

The BB has failed on my Galaxy Ultra 2010 but I'm having problems finding a sugino as fitted but I don't think the BB was a sealed unit and grit has got in so thinking of changing any way do you think a shimano XT/XTR will fit, or is there a better option ?

The Campag shifters will work with almost any double or triple chainset. The BB will depend on the chainset, as will the front mech.
