Hi,
Already thinking on the new season coming up and disputing my self in rebuilding my old 2011 prd fireball witch has been pretty good to me, and has given me two club championship, or buying a new one. I have talk to different builders, some of them say that the new one has better performance with new ports and some of them say that is the same thing besides the new crank bearing.
I just wondering if anybody here has any experience with both and what your input is!
Thank you
