The threaded end of this spoke measures at 11 29/64 inches (halfway between the 11 7/16 and 11 15/32 marks on the measuring tape). A metric tape would make measurement easier, but let's calculate: 29/64 is 0.453125, and so the length measures as 11.435125 inches. (Yes, I know that the number of decimal places exceeds the precision of measurement, but digital calculators give you the extra digits at no extra cost.). Multiplying that number by 25.4 to convert to millimeters and lopping off meaningless decimal places gives 290.9mm. The ruler and the manufacturer's identified spoke length agree very well. | The threaded end of this spoke measures at 11 29/64 inches (halfway between the 11 7/16 and 11 15/32 marks on the measuring tape).
