Bottom bracket question

discurio

Hi all,

I had been having a creaking noise coming from the left hand crank area, i assumed it was the pedal as i had one destroy itself a few years ago with similar sound when i pedaled.

Changed the pedals and the noise continued. So decided it was the bottom bracket making the noise. I have a FSA gossamer chainset and stupidly thought that i could just fit a 105 BB (which i now have as a spare :roll: ) and it would be compatible. That will teach me for not checking.

So I'm stuck on my day off at home with a bike in bits i need to fix. When i looked at the threads for the original BB they are quite dirty and covered in fuzz. Took to them with a wire brush greased the hell out of them and re-installed them to the bike and it seems to have fixed the problem.

Now after all that my question. When I took the original BB out of the bike there was no spacers or seals of any type on the BB. Whenever i have fitted similar BB's to my mountain bike there was always some spacers between the BB and the frame.
Should i have some there? this would explain the water getting into the threads and causing the problem.
The bike is a Focus Cayo, and the Chainset is a fsa gossamer MegaEXO (I think)

Sorry for the long post. Dont even get me started on the missing BB tool and the tantrum that ensued

road bike cranksets dont use any spacers on the External bearings.
