If your bike still has the original square taper BB, you need 3 tools:

http://www.rose.nl/artikel/cyclus-brack ... aid:249797
http://www.rose.nl/artikel/tacx-borgrin ... /aid:22528
or similar of another make
For a later square taper BB you need this piece:

The older one consists of several pieces and can be adjusted. The later one enables easier and faster instalment, but can't be serviced or adjusted.
Normally your bike should have the old style, unless replaced by new style at some point.
