Hey all, I own a mid 70s Takara (I posted it in the Japanese bikes thread here I believe). Anyways, I think the bottom bracket is pretty much done for on it. When turning the cranks under pressure there are two distinct spots on every rotation that "clunk" (can't think of any better description besides that, sorry). I do have a new bike, a Giant Defy 2, which I love dearly. But I still do love the silky ride of my old steelie and don't want to let her go because I need a "commuter" bike as well. I wont be taking my new bike around campus to get to class/to go to the store/for leisurely rides mainly because I would hate for it to get stolen. Any advice/help would be great, like... can it be repaired? if so, how much do you think it would cost for a local shop to do so? or can I do it myself? Sorry for the long-winded post.

Happy riding!
Charlie
