i think you can if the BB on the frame is a euro type? or if it's a US size then just get yourself a DMR wonder cup (someone is selling something simular in the for sale section)

Gusset wondercups in this for sale section are what you need

not if his frame has Euro size BB as they will be the correct size already and have threads in them.
