This is the motto of iGaging, one of the largest makers of measuring tools (who incidentally have no monopoly on accuracy). They’re one of many top companies doing great work in this very important field. Bicycle mechanics are in the most technical era of our industry but accuracy has never been optional.
Going back to the 19th century, bicycles were among the first widely used machines with precision. Ball bearings and tensioned wheels depend on tolerances that were tighter than engineering of the past. Ever since that time, mechanics are accustomed to frequent measuring while building and repairing bikes.
A rule in measurement—whenever possible use tools that are more accurate than you strictly need. Granted, much bike work can be done without measurement, experienced eyes can judge, compare, and test without knowing the precise numbers. Today, however, mechanics want to understand quantified guidelines, follow (and sometimes bend) them, keep records, and perform useful testing. Read more →
