Quick question for all you ST'ers:

I currently ride an Orbea Orca, which I use for triathlons, road riding...basically an all purpose bike, and am considering making the change to a more triathlon-specific set up. I am wondering how I should go about doing this....the picture of Craig Alexander riding in the 5430 Half is an option http://insidetri.com/...articles/2888.0.html, but I don't really know how much of an improvement this will be. Any suggestions, ideas, etc. would be greatly appreciated.

Thanks!
