Here is my question:
Superlight, why must you bike meet the UCI regulations? Have you ever once raced in a race where bikes have been weighed? What category is it that you race within anyway?
The first year the UCI-rules for Time Trial were adjusted, we went to attend the bavarian (not german) TT championships in the masters class (not elite...). This race has about as much importancy as your average club weekday training race. All participants do this in their spare time as a hobby, no one gets payed for that, everybody travelled there at own cost.
We were greeted by the officials with the rulebook and ruler (pun intended) in hand. Some people had to adjust their aerobars or dismount them at all.
So just don't be too sure about not being checked...
