Aha. You are defending them because you are guilty.

I've had to clean up the mess after assholes using chain bits. You are absolutely wrong about them being kind. They can and will cut up a horse's mouth.

Come ride my Arab or Mustang who BOTH go very well in it. I've yet to ride a horse/donkey/or mule that DIDNT like it. They certainly arent ruined , if weather permits this sunday i'll get video of me riding jugheaded mustang in it. Arab is permanently retired (bad legs) otherwise I would ride him in it to.
Now if you want cruel a bicycle chain bit is cruel.

How do they actually cut up the mouth?
