Right so I've got my hands on a trek 7000 mtb frame and I'm in the process of building it up. Originally I had planed on using a bottom bracket I had lying around (for 68mm shell)but the trek frame is for a bottom bracket with 73mm shell.
The axle itself is more then long enough to accomodate the cranks so as I'm broke after buying all the other bits I was wondering if it was possible to get spacers of some sort to fit in both sides of the shell between the bottom bracket itself and the cups to make this set up work at least until I have the funds for a new one.
I can't see any major problems as the XTR/XT hollowtech chainset uses a simular system for 73mm bb shells, but I was wondering has anyone done something simular or would I be signing my/my bike's own death warrent if I did this?
I hope someone can help!
