Stronglight bottom bracket bearing replacement
I recently acquired an nice T.S. Issac frame and fork from a shop that has parted out the Campy bits from the bike to be sold separately. This bike is circa 1980. I was happy to have the Stronglight bottom bracket with a titanium spindle along with the frame. It has two sealed bearings that are held in place with a drive side and non-drive side cup that acts as a retainer for the sealed SKF bearings. I have searched the internet for a pair of these bearings which are a 61903 RS1 which is the SKF number. Everything that turns up is a millimeter narrower that the ones in this bottom bracket, namely 17x30x7mm. My bearings are 8mm wide. I am inclined to try to maintain the original bearing quality of the original if I possibly can. The original SKF bearings have "France" embossed on the seals. I would be happy with a pair made in Japan. Not interested in Chinese knockoffs based on prior experience. I would appreciate any suggestions to find the replacements. I am wondering if having a 7mm instead of 8 is that important. I could let the non-drive side cup thread inside the shell a couple extra millimeters maybe? Thanks
