Thanks Tom, I never knew what the 4 was and did know the 3 but lapsed in the memory. The 10 has a few, I know this from fitting roo many Esge kickstands. These have the 10 1.5, most kickers and 10mm threads are 1.25, and Campy and other 10mm axles are finer and maybe 1mm, as in 25 per inch. Note that in the metric system, the diameter of the stock is followed by the distance between threads, not 'how many per distance'as in the fractional (often mis-labeled 'inch' , 'English', and 'American')
Sheldon 'lexicographer' Brown is another walking enecyclopedia of
informationand can provide fore fodder for this thread thread.
