Ahhahahahahahhahahahahahah

Edit: Oh, uh no hehe. Shimanos smallest cartridge bb is 107mm. They used to have a 103 but is not produced anymore. Chucksbikes has a fsa ultimax in 103 on their site still. You might want to call around some shops but it's not in any of the regular catalogs (103 cart bb's). Maybe some of the other shop guys here have some leads. If you're not going to go local you can find 103 bb's on ebay and other webstores.

Campy makes a 102 but that's ISO not JIS.
