you know what brand cranks are those?
shimano BB's are JIS taper, which are thicker than ISO taper (e.g. campy, miche)
if they don't go deep enough the cranks that came with your pug they'll be better off taking ISO taper... think someone posted a link to a really cheap campy one for under £15 you can find it on gbcycles.co.uk
then you've got to look out for the length now. if a shimano 110mm gives you a perfect chainline you'll definitely want a longer ISO taper one... i can't tell you how much longer though... no experience with that...
