Just out of Curiousity... Carbon

HOWEVER, there are plenty of carbon track bikes around, and they are high performance tools for use in a velodrome, they are impractical for road use and the people who build these up with mountain bike handlebars and such are known as "Morons"

Impractical? People say that about steel track frames with tight clearances, lots of overlap and steep angles... But that doesn't seem to stop other people from riding them without problems..
