|BB size for a Giant TCR?||Xoc|

Can any one tell me what size bottom bracket I need? I have a 1999 Giant TCR-1r, with a Shimano 600 double crank on it. The BB that I have has developed some play, and I need to replace it. I can't find any details as to what size it needs.

|English thread.The 9 speed ultegra doubles #65xx series use a 109.5 splined spindle. The 8 speed 600/ultegra doubles #64xx series used a 115mm tapered spindle. Since there was no 600 8 speed in 1999 I have no clue what you have on it. Model # should be on the back of the crank arm.|

|Sorry..I should have mentioned...it's a 99 frameset built with an 8 speed 600 group.
I took the old BB into the shop with me...68 x 115 was it. Thanks for the help.
