A Dura Ace BB
An XTR BB
Are they interchangeable? What is the difference. I know what I'd prefer to buy if they are exactly the same things...
And if I were to stick to the MTB BBs, the XT BB
is $45.66 - what is the difference between it and the $63.93 XTR BB?
Shimano's website is not very forthcoming at revealing the particulars of each BB (anodising excepted) that accounts for the price difference between them all .
I know that the MTB BB and the Road BB have difference shell widths, but are the threads the same (British compatible with MTB std thread)? I have the spacers that would allow me to run the road BB in my BB BB shell, and the plastic sleeve, so it seems possible to interchange them. Are the road and MTB spindles the dame dia.?
Hmm... that's all the info and questions I can think to present at the moment.
