For the love of God...how about I just say what so many of you really want to hear:

Nothing makes a single shred of difference, I'm full of crap. I have no scientists following me around with 1.5 million dollars worth of test equipment therefore everything thing I claim, no matter how small that claim may be, is complete and utter BS (and I am an imaginative moron for having though it in the first place).


OP...listen to these guys. Nothing you will buy will make a crap-bit of a difference. Buy a GMC bike from Amazon and be happy because this is literally the best riding experience you will ever get. Nothing...and I mean NOTHING will make even the slightest difference in performance no matter what anything tells you...because you will never have the die hard scientific data to prove it.

There...you guys happy with that response?
