Octalink bb replacement help.
My current bb are 68x113mm.
I just bought a replacement bb but it is 73x113mm and it comes with a 5mm spacer.
Question is, do I put the 2x2.5mm spacer on the drive side or non-drive side?
Or do I put 1 on each side?
Can anyone help?
Thanks...

Keep on climbing
I'm pretty sure the 68 vs. 73 measurement has to do with the width of the bottom bracket shell in the frame itself; have you tried to see if that BB will even fit in your frame? The 113mm measurement is the length of the spindle.

Yup that is correct.... 73 is the BB shell width....use the spacers if the shell is 68

If you look on the BB there will be a model number. Go to the Shimano website and download the PDF service instructions for your BB. This will explain where the spacers go.
