yes; and it depends on the crank set you choose and the width of your frame.

This one uses cone style bearings - which are included: http://www.amazon.com/Pyramid-Piece-Bottom-Bracket-Conversion/dp/B000AO9O12/

These require a separate BB:

Hi Bill;

I had not noticed that......

From the appearance of it, the axle could probably be replaced with one of the many others Pyramid catalogues.

1 pc are generally called American. Have not heard of "mid" before. Where did you see that term?

I'd go with the SBS conversion. You still have to pick a BB, which will depend on the crankset you choose.

If you pick the Pyramid kit, you may have to change the axle depending on the crankset you choose.
