This should be what you need for a der hanger:

part no. 989-4271 or 989-4275

BB size depends a bit on whether you want to do standard (geared) build or do a single speed build.

The BB thread should be BSA (British), the shell width is most probably 68mm you should measure this, though. The spindle length depends on the front derailleur / and crank you want to use.
