Hello,

I plan to enter tournaments and I wanted to clarify a rule because I want to use certain colors of ratchet parts.

The following is taken from the “Legal Equipment” section, “Additional Equipment Regulations”, green portion:

Swapping Part Components/Disassembling Parts: If a Part can be disassembled via non-destructive means, components of that Part may be replaced with an identical substitute from another Part.  

My interpretation would be as long as I am replacing a part with a different color that has the same protrusions or height it should be a legal part. Is my understanding correct?

As long as you don't make a ratchet that doesn't exist yet (ie 1-70) you can make any color combination of contact and skirt that you want in WBO tournaments.
