IRONMAN IS THE ONLY WAY TO GO. Call and ask for Nate, he is a racer himself and a very good one too. I myself use ironman sprockets and did even before they sponsored me. I have never had a problem and as everyone has stated above they wear great. I will be using them at this years ISDE as well as all of my local races simply because they are the best. Send me an email to
Billyburnsins@hotmail.com and I will call Nate and see if I can get you a deal. They also sell packages that have a discount built in.
