I wonder what size the front wheel axle nut on the Super Soco TS has.

It is M12 but I'd like to know the thread picth if anyone knows how to measure so I can get another nut that fits.

My guesses are 1.25 1.5 or 1.75. Standard IS sizes says M12 should be 1.5. 1.75 is coarse and the other lower sized ones are called fine thread so which one fits my bbbbbbike? 😀

thanks

For TS. Probablly also for TC and TC-Max. Front wheel axle nut size is M12 fine thread or pitch of 1.25. Other sizes are as said 1.5 and 1.75 but they are called coarse thread. 

The standards usually have one fine and one coarse thread for each nut or bolt. Fine threads are used for veichles for its better protection against vibrations and of not getting your nuts unscrewed in use.
