Intro:
My Balfa BB7 has been squeaking for a while so I decided to take it apart and lubricate it. Once I got the frame apart and removed the linkage plates, I noticed a problem. For one, there were metal shavings coming out of the bearing's rubber seals. The other problem was the pivot axle rotated in clicks as though there were a ratchet mechanisim in there. After a little searching around I found the bearings and also recieved some helpful information from Jamie at http://balfa.co.uk (A good place to buy Balfa parts). Since it was somewhat difficult to find the information I decided to document it and post it here.. enjoy!
