Inner Bore Dimensions
There are 16 different molds in the NEW BSA Wheel set. Below is our data regarding this info. Measured with precision pin gauges with 0.0002″ accuracy. Our mathematical calculations are based upon our best attempts at measuring data. We measured 50 wheels of each mold (800x wheels) and compiled the data below. Wheels are coming along very well. Most molds are dead spot on.
Best results are wheels with the smallest average deviation and smallest bore size. View Excel Spreadsheet
MODE: The most common value in a data set.
Typical measured diameter of all wheels (TMD): 0.0970
Our favorite wheels are the #9 and #11 molds.
