So heres the scoop, I bought a year 2000 8000 SLR Frame. Stripping my XT parts of another bike and putting them on this. I called the Trek dealer and they said the bottom bracket was 73x113 octalink to fit my LX Cranks. I put it on and the front sprocket is to close to the chainstay. I put he 68x121 that came off my old bike and it seems to be fine, It fit in nice and tight and seems to look ok, I have not hooked up the rear delraileur yet. Can I hurt the frame by using the 68mm x 121?

Any knowledge on the bottom brackets would be awesome, the 68x121 and the 73x113 seemed to be the same size except for the axle was longer on the 121.
