I would say my CRX is one of the most aggressive (in terms of geometry) in Australia. I have my seat up high, have the stem angled max downwards, and the spacers above the stem.
Very aero, and fast - especially with a set of Continental 4000S (great tyres, they don't cut up like the ProRace2 or Evo Corsa CX and have great traction).
I passed a guy riding a Soloist with Zipp 404s last week, and boy was he embarrssed. He did have the edge on acceleration from the traffic lights though
