If you have the technology to make your own rings, I would hope you would know how to measure teeth on an existing ring.

If measuring was that easy, I would have done it. BUT measuring isn't that precise! You always have some inaccuracies.

That's why I asked if somebody knew the measures of the teeth!!

5. ## Ok then...

Here you go. Have funn with it, this is for a 42T chain ring.

6. ## Thank you very much!!!!

The 2 is the distance from the center of the small cicle to the outside of the big circle.

to me it seems to be the distance from the line wich connects the two circles' centres to some small line outside the large circle and i don't know what that small line is.

i marked the arrow heads red and the line, i'm talking of, light green. whats the green line?

The GREEN line shows the width of the tip of the tooth.

The BLUE area is the 'beveled' or 'chamfered' profile of the tooth.
