Hi everybody,
I purchase a second hand mountain board called "lion canyon" from scrub and I want to change the wheels so I can use it on soft sand.
I have to build some "axis extension" because the axis of the new wheel will be wider than the normal one, so I need to know what is the nuts references (size of thread and diameter).
I thought it was M10 with thin thread (1mm), but it's not exactly this as i can not screw a M10 nut on the axis (I can do 3 rotations and then it gets blocked).

Any help would be greatly appreciated!

Thanks !
