I just replied to your TJT post, but I'll repeat it here...
I'm gonna test out my bike in a couple hours when my wife and kid leave for the day : )
Right now I have the six heaviest rollers made even heavier by me putting 2 split-shot fishing weights in each roller.
We'll see soon if I need lighter or heavier...
Gotta get ahold of TJ and get his GPS to see what my new top speed is like too...
