Hi,
Time trial bikes are about the coolest bikes out there IMHO.

I am partial to time trial setups versus triathlon setups. The lower bars make them look extra cool.
One reason why I race time trials is to rationalize owning a bike like this

:
This is me from a TT last fall with the bike in a slightly different configuration:
Please forgive the tilted helmet. I guess I needed to tighten it up a bit.
I certainly train on my TT bike periodically but training on a TT bike at 23-26 MPH on a MUP is probably not the safest or wisest thing to do.
stapfam, my TT bike certainly did not costs $10,000. That's what I tell my wife and if I spent that much on mine, I certainly didn't do it all at once.
