Im changing my chainset to a Deore LX (M563) and after looking on Sheldon Browns bottom bracket size guide it suggests a BB length of either 107 or 113 depending on seat tube diameter, my bike has a standard seat tube , I have a brand new Shimano UN 54 BB with a width of 110 and was wondering if i could i use this as its right in the middle of the two suggested.
It seems a shame to leave the UN 54 on the shelf.
