Hey folks, I have a very quick question that I am concerned about. I just recently purchased a used Srm training system (professional not the Dura -ace 10) and the chain rings seem to have broken teeth. So with the help of slowtwitch members, I was made to understand I change them to other chain rings. Well here is the issue I am currently running Dura-Ace 10, will there be an problem with my group if the professional crank was not spec’d to run Dura-ace or I am being overly concerned … can you all offer some suggestions


Thanks you in advance….
