Posted earlier in a thread about going tubeless on my road bike this year. I have American Classic wheels and from what I have read, those who work for American Classic use either IRC or Schwalbe tubeless tires as a preference. That is not to say other tubeless tires won't work with American Classic, it is just their personal preference. I was looking at the IRC tires and the http://www.irc-tire.com/en/bc/produc...rmula_tl-rbcc/ and it looks interesting but, I know nothing about IRC tires. Do any of you have any experience with IRC tires in general that you would care to share?
