Q: Where on your web site can I order these wheels?

A: Click on the links in the first column of the tables above.

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:

Round: How close the wheel approaches a true circle. This is irrelevant for lathed 'Speed Wheels'.

Left-Right: How close the sidewall is perpendicular to the wheel hub.

Bore Size: The relative diameter of the wheel bore.

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.

Mold #	Round	Left-Right	Bore Size
1	Okay	Good	Typical
2	Excellent	Okay	Typical
3	Excellent	Excellent	Typical
4	Okay	Good	Typical
5	Okay	Okay	Typical
6	Okay	Okay	Typical
7	Good	Good	Typical
8	Excellent	Excellent	Typical
9	Good	Okay	Typical
10	Okay	Okay	Typical
11	Okay	Good	Typical
12	Excellent	Excellent	Typical
13	Good	Okay	Typical
14	Okay	Good	Typical
15	Excellent	Excellent	Typical
16	Good	Good	Typical

Notes on measurements:

Measurements made in August of 2009. Ten wheels from each mold were randomly selected from 2,000 wheels. The wheels were examined and the results averaged.

In general, all of the wheels are good - much better than the previous wheel version. The difference between the Excellent, Good, and Okay ratings is a few thousandths of an inch.

The bore size on all mold numbers measured within one thousandth of an inch.
