.....was wondering if anyone knew why Litespeed stopped bending the seat tube on the newer Ultimates....?

Then what about the P3????
The rules are really specific, I think the P3 is right on edge..TJeanloz

Doesn't the rule (among other rules) state that for the main triangle tubing, you must be able to theoretically insert a straight line from one end of the tubing to the other? Just out of curiosity, I examined my P3 and determined for myself that you could do this.

From the Cervelo site:

1.3.020

c)Configuration

For road races other than time trial races and cyclo-cross events, the frame of the bicycle shall be of a traditional pattern, i.e. built around a main triangle. It shall be constructed of straight or tapered tubular elements (which may be round, oval, flattened, teardrop shaped or otherwise in cross-section) such that the form of each element encloses a straight line. The elements of the frame shall be laid out such that the joining points shall follow the following pattern: the top tube (1) connects the top of the head tube (2) to the top of the seat tube (4); the seat tube (from which the seat post shall extend) shall connect to the bottom bracket shell; the down tube (3) shall connect the bottom
bracket shell to the bottom of the head tube. The rear triangles shall be formed by the chain stays (6), the seat stays (5) and the seat tube (4) with the seat stays anchored to the seat tube at
points falling within the limits laid down for the slope of the top tube. (text modified on 7.06.00).

The maximum height of the elements shall be 8 cm and the minimum width 2.5 cm.The minimum width shall be reduced to 1 cm for the chain stays (6) and the seat stays (5). The minimum thickness of the elements of the front fork shall be 1cm; these may be straight or curved (7). (See diagram "Shape (1)").

The top tube may slope, provided that this element fits within an horizontal template defined by a maximum height of 16 cm and a minimum thickness of 2.5cm.

_________________________

My reading of it is the the "other than..." language is only in reference to the main triangle; after that sentence, everything else applies to all bikes.
