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.

Yes is the simple answer.

Longer answer is 110 is the same as 107 on the drive side but longer on the none drive side. (Same as the 113 length on none drive side)
 
Hi FluffyChicken
Good to hear from you again
Thanks for the info, I was worried the drive side would hit the chainstay, but now its fitted theres plenty of room.

:D
