Tri bike, rules?

UCI rules are what the road racers are restricted by (those guys that ride the Tour de France). There are also ITU rules that govern the international triathlon racing (and the draft-legal format). USAT has a less stringent set of rules (non-drafting tri), which most every race in the USA enforces (including Ironman, with the exception of the draft zone definition -- which doesn't affect bike configuration at all).

But in general... UCI says that the tip of the saddle can't be forward more than a line 5cm BEHIND the bottom bracket. There are other rules specific to how far forward the aero bars can extend, how high they can be, how "level" they must be, etc...

ITU rules allow a more forward saddle position, but the bike must have road handlebars, and aero clip-ons can't extend farther forward than the brake levers.

AFAIK, the various tri rulebooks don't have frame thickness specs.

I race at about 205-210 Lbs. The first bump and that bike would shatter and there would go my $8K

Freaky...I've seen some pics like this of what I would call Next Generation Tri bikes and they make my 2008 Scott look a little horse-n-buggy

Ceepo makes some great bikes, that one is a little over the top, but i think it will be a name you see more of in the states in a few years. I love their wheels. i think that bike can handle well into the 250lb range without too much worry.

I saw a news thing a couple of years ago about BYU university doing some testing on that lattice type carbon configuration.  They made a bike out of it and a small scale airplane.  I wonder how long the technology has been around?  I thought they were part of the innovation but maybe not.
