Q: Where can I find information about the mold numbers for BSA wheels?

A: Right Here.


Mold Characteristics

The table below provides the characteristics of the various BSA wheels. The definitions of the columns are:

Important Note
Within each mold family, there are occasional bad wheels. This is mostly due to the manufacturer not allowing the molded wheels to cool sufficiently before mold removal. Always spin test each wheel, eliminating wheels with excess side-to-side wobble.

In the table below, the premium matched wheels are identified with a green background.

2 Excellent Excellent Typical
3 Good Okay Typical
4 Good Good Typical

Notes on measurements:

  1. Measurements were made in June of 2015. Ten wheels from each mold were randomly selected from 1,900 wheels. The wheels were examined and the results averaged.

  2. In general, all of the BSA wheels continue to be good, although there were a few changes in ranking. Note that the difference between the Excellent, Good, and Okay ratings is just a few thousandths of an inch.

  3. Important Update - Late in the summer of 2015, BSA began shipping wheels that were molded in refurbished molds. The new wheels are slightly "blacker", and many of the mold numbers appear to be blurred or double-printed. Molds #2 and #15 are still premium, but only some of the #6 and #7 wheels are premium. So, if you are picking out wheels from kits or from replacement sets, #2 and #15 wheels are a safe bet
