[TurboTurtle]

when did this frame start having a 31mm seatpost size ? Was it 2004 or 2005 ? Also, when did it start with the triangular kind of top tube (instead of the previous round shape) -> was this 2003 or 2004 ?

Thanks !

2004 catalog - "New for 2004...we have increased the stiffness of the frame with an oversized seat tube...". "31.6 seat post"

Looks like the shaped top tube also started in 2004.
