Adding the "training" wheels...

Remember when you were a kid and you had training wheels on your bike...
That is what I have now... training wheels

The problem is, I do not deflect the bike enough with my weight to keep the angle rather small.  After weighting the bike down with 200 lbs last week and recording the deflection, I decided to increase the amount of carbon fiber on the side rails.  The purpose was to decrease the deflection (35mm).  Well it worked so well that the bike deflects between 12 and 15mm with my weight. That keeps my training wheels higher off the ground. Thus the angle of lean for the bike in order for the training wheels to hit the ground is a bit steeper in feel than I expected.  The calculation:

I designed the wheel housing so that I can take up to 110mm wheels.  So I will go to bigger training wheels -- initially anyway.

As a side-note: The chain-line is lllloooooonnnnnggggg:
