What size & brand BB came out?
I just replaced my cranks & BB from old LX square taper to new octalink.
The old BB was 113mm & I ordered a 118mm.
The 118mm was to narrow with octalink cranks (the octalink seems to squeeze tighter on the spindle) so I ordered a 126mm and it worked just fine.
If you already have a splined BB I would assume you could order one the same size that came with the bike.
