Have you looked at these brakes for the front brake?? http://www.tririg.com/articles.php?id=2 ... Production

They aren't released yet, but I have one on pre order due for shipping by the end of the month. I would be willing to ship it to you to use for the paralympics if you wanted? (PM me if interested)
The Felt looks like a fairly standard fork bolt set up on that frame from what I can see on internet images! Unless the bolt goes the opposite direction to normal??
If nothing else all the TRP brakes I've ever seen weigh massively more than competitors.
As said above world class tubs could buy you another 5+watts. I'm thinking Dugast silks. 99€ each is too much for me (a 20min 10TT man) but the olympics is everything.
Also carbon derailleur mods + pulley wheels from fibrelyte?
Have you considered contacting Simon Smart at http://www.smartaerotechnology.com/wp/
" onclick="window.open(this.href);return false; they might be able to help or offer some sponsorship?? As having a world champ and potential paralympic gold medalist could only be good PR for them! (you don't ask, you don't get!) Possibly the same with USE as their Tula aerobars are considered to be the fastest UCI legal thing out there and I know they've been testing a new version with Hutch for the last 12 months.
And most of all GOOD LUCK!
