Try asking at the Internet Bridgstone Owners Bunch (IBOB) mailgroup.
They will give you more than enough Bridgestone information, and offer a careing home for your bike. You will have to search and subscribe to it.
The BOB phenomena is slightly strange but endearing. For those who dont know, BOB has developed from a bunch of slighty conservative bicycle enthusiasts into a catch-all adjective describing the appreciation of appropritate technology and design upon which technolgy may advance, but not improve.
